description: Topological insulators are characterized by a nontrivial band topology driven by the spin-orbit coupling. To fully explore the fundamental science and application of topological insulators, material realization is indispensable. Here we predict, based on tight-binding modeling and first-principles calculations, that bilayers of perovskite-type transition-metal oxides grown along the [111] crystallographic axis are potential candidates for two-dimensional topological insulators. The topological band structure of these materials can be fine-tuned by changing dopant ions, substrates, and external gate voltages. We predict that LaAuO$_3$ bilayers have a topologically-nontrivial energy gap of about 0.15 eV, which is sufficiently large to realize the quantum spin-Hall effect at room temperature. Intriguing phenomena, such as fractional quantum Hall effect, associated with the nearly-flat topologically-nontrivial bands found in $e_g$ systems are also discussed.

description: We study the detectability of neutrino bursts from nearby direct black hole-forming collapses (failed supernovae) at Megaton detectors. Due to their high energetics, these bursts could be identified - by the time coincidence of N >= 2 or N >= 3 events within a ~ 1 s time window - from as far as ~ 4-5 Mpc away. This distance encloses several supernova-rich galaxies, so that failed supernova bursts could be detected at a rate of up to one per decade, comparable to the expected rate of the more common, but less energetic, neutron star-forming collapses. Thus, the detection of a failed supernova within the lifetime of a Mt detector is realistic. It might give the first evidence of direct black hole formation, with important implications on the physics of this phenomenon.

description: Some of the first stars could be cooler and more massive than standard stellar models would suggest, due to the effects of dark matter annihilation in their cores. It has recently been argued that such objects may attain masses in the 10^4--10^7 solar mass range, and that such supermassive dark stars should be within reach of the upcoming James Webb Space Telescope. Notwithstanding theoretical difficulties with this proposal, we argue here that some of these objects should also be readily detectable with both the Hubble Space Telescope and ground-based 8--10 m class telescopes. Existing survey data already place strong constraints on 10^7 solar mass dark stars at z~10. We show that such objects must be exceedingly rare or short-lived to have avoided detection.

Two-Part Forecasting for Time-Shifted Metrics

description: Katz, Savage, and Brusch propose a two-part forecasting method for sectors where event timing differs from recording time. They treat forecasting as a time-shift operation, using univariate time series for total bookings and a Bayesian Dirichlet Auto-Regressive Moving Average (B-DARMA) model to allocate bookings across trip dates based on lead time. Analysis of Airbnb data shows that this approach is interpretable, flexible, and potentially more accurate for forecasting demand across multiple time axes.

Doublet-Triplet Splitting in an SU(5) Grand Unification
Creators: name: Yamashita, Toshifumi
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a new solution to the doublet-triplet splitting problem which also works in a supersymmetric SU(5) grand unified theory and is testable at TeV-scale collider experiments. In our model, the SU(5) symmetry is broken through the Hosotani mechanism. Thanks to the phase nature of the Hosotani-breaking, the "missing VEV" can be realized even in an SU(5) model. A general and distinctive prediction of this solution is the existence of light adjoint chiral supermultiplets with masses of the supersymmetry breaking scale. Though these disturb the gauge coupling unification, it can be recovered keeping the unified gauge coupling constant perturbative by introducing additional vector-like particles, which may be also observed in the upcoming collider experiments.

Remarks on Income Contingent Loans: How Effective Can They Be at Mitigating Risk?

Income-contingent loans

Financial risk management

description: A well-known principle holds that equity provides better risk sharing opportunities than debt, but that there are greater enforcement problems associated with equity. Income contingent loans (ICL) represent an efficient (low transactions cost) way of implementing equity contracts for human capital.1 The amount the individual repays is dependent on his or her income. While it seems natural to link ICL with investments that increase the value of human capital — most notably education — there is no necessary reason to limit it to such investments.

description: Transport properties of a superconductor-semiconductor-superconductor (S-Sm-S) junction with superlattice structure are investigated. Differential resistance as a function of voltage shows oscillatory behavior under the irradiation of radio-frequency (RF) waves with the specific frequency of 1.77 GHz regardless of the superconducting materials and the junction lengths. Experimental data are quantitatively explained in terms of the coupling of superconducting quasiparticles with long-wavelength acoustic phonons indirectly excited by the RF waves. We propose that the strong coupling causes the formation of novel composite particles, Andreev polarons.

Bridging constructions in Tsezic languages
Creators: name: Forker, Diana
name: Anker, Felix
Publisher: name: Zenodo
Year: 2019

description: This paper treats bridging constructions in the Tsezic languages (Bezhta, Hunzib, Khwarshi, Hinuq, and Tsez) of the Nakh-Daghestanian language family. We describe the syntactic and semantic properties of bridging constructions based on corpus data from all five Tsezic languages. Bridging constructions are defined as bipartite constructions that consist of a finite reference clause, which is followed by a non-main adverbial clause that functions as the bridging clause. The adverbial clause contains a variety of temporal converbs with general perfective converbs being more common than other types of temporal converbs. Reference and bridging clauses are both a target for additions, omissions, modifications and substitutions. Bridging constructions are primarily found in traditional oral narratives such as fairy tales where they index the genre and function as stylistic devices to express parallelism. Within the narratives they are often used to indicate episode changes and can be accompanied by switches of subject referents or locations.

description: We show that the distinct differences of low-lying THz-frequency dynamics between type-I clathrates with on-center and off-center guest ions naturally follow from a theoretical model taking into account essential features of the dynamics of rattling guest ions. Our model analysis demonstrates the drastic change from the conventional dynamics shown by on-center systems to the peculiar dynamics of off-center systems in a unified manner. We claim that glass-like plateau thermal conductivities observed for off-center systems stem from the flattening of acoustic phonon dispersion in the regime |k|
Random models and heuristic algorithms for correlation clustering problems on signed social networks
Creators: name: Wahid, Dewan Ferdous
Publisher: name: University of British Columbia
Year: 2017

description: In social sciences, the signed directed networks are used to represent the mutual friendship and foe attitudes among the members of a social group. Recent studies show that different real-world properties (e.g. preferential attachment, copying etc.) can be observed in the web-based social networks. In this thesis, we study the positive/negative - in/out - degree distributions in three online signed directed social networks. We observe that all signed-directed degree distributions in the web-based social networks with multiple edges possibilities (in both directions) follow a power law with exponents in the range 2.0<= \gamma <= 3.5. We present three random models, which capture the preferential attachment and copying properties, for web-based signed directed social networks. The signed-directed degree distributions in the networks simulated by the proposed random models also indicate a power-law trait with an exponent in the range 2.0<= \gamma <= 3.5. We also present a heuristic algorithm for the Correlation Clustering (CC) which is a class of community detection problem in the signed network. The CC problem can be defined as follow: for a given signed network, finding an optimal partition in the vertices such that the edges inside a group are positives and the edges between two groups are negative. We present the algorithm based on the relaxing integer linear programming formulation of the minimum disagreement CC problem and rounding the approximate ultrametric distance matrix by using a given threshold. The experimental results show that, in the random signed G(n,e,p) network, the runtime of this algorithm is nearly independent for the cases e>= 0.4 and p<=0.6 , where e and p are the probabilities of connecting two vertices by an edge and an edge to be positive respectively. But this algorithm does not give any convincing argument in the variation of the minimum disagreements due to the changing of the given threshold. We also apply this algorithm to the International National Bilateral Tread Growth Network derived from the bilateral trading data in 2011-2015 from the International Trade Center (ITC) to identify the groups of countries with average positive trade growth.
Bridging constructions in narrative texts in White Hmong (Hmong-Mien)
Creators: name: Nerida Jarkey
Publisher: name: Zenodo
Year: 2019

description: This chapter examines bridging constructions in narrative texts in White Hmong (Hmong-Mien, Laos). Bridging constructions occur in all the texts examined for the study, with frequency and type of construction varying according to narrator and text type. Recapitulative linkage is far more common than either summary linkage, which is limited to first-person narratives and reported speech, or mixed linkage, which serves to summarize direct quotations in oral and written texts with a more literary character. In terms of function, the analysis shows that bridging constructions in White Hmong narrative texts work cohesively, linking one unit in the event line of the narrative to the next and thus serving to progress the main sequence of events. The event described by the bridging construction is constructed as a salient point in the event line, and becomes the base from which the next unit in the event line of the narrative proceeds.

Given two natural numbers g and n satisfying 2g+n-2>0, the program generates all genus g stable graphs with n unordered marked points. Each such graph determines the topological type of a nodal stable curve of arithmetic genus g with n unordered marked points. Our motivation comes from the fact that the boundary of the moduli space of stable genus g, n-pointed curves can be stratified by taking loci of curves of a fixed topological type.

description: The one variable Krawtchouk polynomials, a special case of the $_2F_1$ function did appear in the spectral representation of the transition kernel for a Markov chain studied a long time ago by M. Hoare and M. Rahman. A multivariable extension of this Markov chain was considered in a later paper by these authors where a certain two variable extension of the $F_1$ Appel function shows up in the spectral analysis of the corresponding transition kernel. Independently of any probabilistic consideration a certain multivariable version of the Gelfand-Aomoto hypergeometric function was considered in papers by H. Mizukawa and H. Tanaka. These authors and others such as P. Iliev and P. Tertwilliger treat the two-dimensional version of the Hoare-Rahman work from a Lie-theoretic point of view. P. Iliev then treats the general $n$-dimensional case. All of these authors proved several properties of these functions. Here we show that these functions play a crucial role in the spectral analysis of the transition kernel that comes from pushing the work of Hoare-Rahman to the multivariable case. The methods employed here to prove this as well as several properties of these functions are completely different to those used by the authors mentioned above.

description: In his celebrated memoirs, Nelson Mandela recounts the story of having to battle his political adversaries and friends alike to convince them of the necessity of launching an armed movement in their fight against the unbearable brutalities of apartheid. Even his closest allies and supporters resented the idea of resorting to such a controversial strategy, one that raised deep moral questions and required complex implementation capabilities. They opposed his views until he was able to explain that the battle for freedom and prosperity is never an elegant linear path, and that sometimes one has to take unexpected detours and rely on trial-and-error tactics. He finally got his way. And yet the most difficult challenge occurred after his recommendations were eventually validated by his peers, who then asked him to actually implement them. Mandela had no choice but to accept that responsibility. He quickly realized how testing it can be to move from impeccable theoretical reasoning to concrete action on the ground. He writes: “I, who had never been a soldier, who had never fought in battle, who had never fired a gun at an enemy, had been given the task of starting an army. It would be a daunting task for a veteran general, much less a military novice.”

description: We report the observation of the Inverse Cotton-Mouton Effect (ICME) i.e. a magnetization induced in a medium by non resonant linearly polarized light propagating in the presence of a transverse magnetic field. We present a detailed study of the ICME in a TGG crystal showing the dependence of the measured effect on the light intensity, the optical polarization, and on the external magnetic field. We derive a relation between the Cotton-Mouton and Inverse Cotton-Mouton effects that is roughly in agreement with existing experimental data. Our results open the way to applications of the ICME in optical devices.
The form and function of bridging constructions in Eibela discourse
Creators: name: Aiton, Grant
Publisher: name: Zenodo
Year: 2019

description: Discourse in Eibela utilizes extensive repetition and summarization of events as a means of bridging discourse episodes. These bridging constructions consist of a main reference clause at the end of a unit of discourse, which is immediately referenced by a non-main bridging clause at the commencement of the following unit of discourse. Bridging clauses may be formed by medial clauses initiating a clause chain, and topic clauses that are embedded within another medial or final clause. Differing units of discourse are often accompanied by differing forms of bridging construction, with clause chain boundaries featuring verbatim repetition of clauses, and larger paragraphs being bound by bridging clauses utilizing anaphoric predicates. Bridging constructions have been previously shown to serve various functions in Papuan languages, including thematic continuity, reference tracking, and event sequencing, which will also be illustrated in the current discussion of bridging constructions in Eibela.

description: This chapter is an introduction to and summary of "Income Contingent Loans: Theory, Practice and Prospects." An International Economics Association workshop on the broad topic of ICL (income congruent loan) was held at Dhurakij Pundit University in Bangkok in April 2013 with Professors Joseph E. Stiglitz and Bruce Chapman. This workshop covered: the conceptual and theoretical underpinnings of ICL; the costs and benefits of different types of higher education student loans; and potential contingent loan policy applications beyond higher education. A number of participants presented commentary during and after the workshop, summarising their thoughts on the discussion, and examining, among other things, advantages and disadvantages of particular features of different ICL programs, lessons learned, unresolved questions, and future prospects and challenges. This volume contains revised versions of the presentations and commentaries presented at the workshop.

description: Recently, a diffusion Monte Carlo algorithm was applied to the study of spin dependent interactions in condensed matter. Following some of the ideas presented therein, and applied to a Hamiltonian containing a Rashba-like interaction, a general variational Monte Carlo approach is here introduced that treats in an efficient and very accurate way the spin degrees of freedom in atoms when spin orbit effects are included in the Hamiltonian describing the electronic structure. We illustrate the algorithm on the evaluation of the spin-orbit splittings of isolated carbon and lead atoms. In the case of the carbon atom, we investigate the differences between the inclusion of spin-orbit in its realistic and effective spherically symmetrized forms. The method exhibits a very good accuracy in describing the small energy splittings, opening the way for a systematic quantum Monte Carlo studies of spin-orbit effects in atomic systems.

Online and offline bridging constructions in Korowai
Creators: name: Vries, Lourens De
Publisher: name: Zenodo
Year: 2019

description: Korowai has two main types of bridging constructions, recapitulative linkage (also known as ``tail-head linkage'') and summary linkage with generic verbs of doing, each with two subtypes that follow from the grammatical distinction between chained and adverbial or thematic types of clause combining. Recapitulative linkage with chained, switch reference marked clauses is by the far the most frequent type of bridging construction. It has three functions. First, a processual function, to give the speaker and addressee a processing pause in between two often lengthy clause chains. Second, it creates chains of clause chains, so called chaining paragraphs. The third function is to enable the speaker to continue referential tracking in the transition from one clause chain to the next. Recapitulative linkage with thematic subordinate clauses shares the processual function wih the chained type but it signals discourse discontinuity: it disrupts the event and participant lines and the speaker goes off the event line. Summary linkage allows speakers to be less specific in the scope of their anaphoric linkage, not necessarily taking the final clause of the previous sentence as their reference clause.

description: Using the AdS/CFT correspondence for strongly coupled gauge theories, we calculate thermalization of mesons caused by a time-dependent change of a baryon number chemical potential. On the gravity side, the thermalization corresponds to a horizon formation on the probe flavor brane in the AdS throat. Since heavy ion collisions are locally approximated by a sudden change of the baryon number chemical potential, we discuss implication of our results to RHIC and LHC experiments, to find a rough estimate of rather rapid thermalization time-scale t_{th} < 1 [fm/c]. We also discuss universality of our analysis against varying gauge theories.

Many kinds of solitons in such optical lattices, including symmetric and antisymmetric lattices, are found under different conditions. We study the influence of the refractive index difference between two different layers on solitons. It is also found that there do not exist cutoff value of propagation constant and soliton power for shifted lattice solitons. In addition, the solitons launched away from their stationary position may propagate without oscillation when the confinement from lattices is strong.

description: Knowledge validation has never been a painless process. It often takes a major, disastrous historical event for even the most self- evident ideas to gain wide recognition. It is therefore not surprising that the Great Recession of 2008– 09 – whose global economic and social cost is still yet to be quantified – has led to a rethinking of many aspects of what might be thought of as the conventional wisdom in economics. This book is about one important area in which there has been a major rethinking – industrial policy, by which we mean government policies directed at affecting the economic structure of the economy. The standard argument was that markets were efficient, so there was no need for government to intervene either in the sectoral allocation of resources or in the choices of technique. And even if markets were not efficient, governments were not likely to improve matters. But the crisis showed that markets were not necessarily efficient, and indeed, there was a broad consensus that without strong government intervention – which included providing life- lines to certain firms and certain industries – the market economies in the USA and Europe may have collapsed. But what exactly is industrial policy? Why has it raised so much controversy and confusion? What is the compelling new rationale for it, which seems to bring mainstream economists to acknowledge its crucial importance and revisit some of the fundamental assumptions of economic theory and economic development? How can it be designed to avoid the pitfalls of some of the seeming past failures and to emulate some of the past successes? What are the contours of the emerging consensus and remaining issues and open questions? The collection of papers presented in this volume and initially discussed at a roundtable try to provide answers to these burning questions. This book is a contribution in the large body of ongoing analytical work that focuses on the rejuvenation of industrial policy in the post- crisis global economy, discusses the evolving conceptions of industrial policy, takes stock of intellectual progress, documents the challenges of implementation, and outlines the remaining intellectual and policy agenda.

description: We noted in the introduction that China, like developing countries all over the world, has been urged to adopt a set of institutions, typically described as “best practices” and thought to characterize the Anglo-American model of market economy. Underlying a successful market economy, it is argued, there exists a rule of law—and by rule of law what is meant is not just any legal framework, but a particular one, what we referred to in the introductory chapter as the “neoliberal orthodoxy,” based on “Chicago School” economics. It is important to place this approach, which focuses on notions such as “secure property rights,” in perspective. It has long been the subject of intense debate among both economists and legal scholars. Although the Chicago School has had enormous influence in thinking about legal and other institutions, it no longer represents the best thinking about the relationship between law and economic policy—far from it. As we explained in the Introduction, as a matter of economics, many of the foundational premises of the Chicago School have been challenged. As a matter of law, the institutions thought necessary for market efficiency have been shown to be far more variable and contingent. And there is more to a successful economy than just efficiency. There is not a single best set of institutional arrangements that work for countries in different circumstances with different objectives. Countries face choices about their institutional arrangements, and the choices about strategy and institutional form are critical, particularly as China puts in place institutional arrangements that will have a long-term dynamic effect on the structure of the Chinese market economy. As China sets out to create a market economy with Chinese characteristics, as it sets out to advance its objectives of creating a harmonious society, as it thinks about institutional designs that provide the flexibility for changing course as it advances in its development (in accord with the principle of “crossing the river by feeling the stones”), it needs to think carefully about the full range of consequences of each of the alternatives—not only for efficiency and equity today, but for how current choices are likely to impact its future evolution. This chapter explains the limitations both of the underlying economics upon which the neoliberal orthodoxy is based and of some of the associated legal principles.

description: We report the controlled integration, via Dip Pen Nanolithography, of monolayer dots of ferritin-based CoO nanoparticles (12 Bohr magnetons) into the most sensitive areas of a microSQUID sensor. The nearly optimum flux coupling between these nanomagnets and the microSQUID improves the achievable sensitivity by a factor 100, enabling us to measure the linear susceptibility of the molecular array down to very low temperatures (13 mK). This method opens the possibility of applying ac susceptibility experiments to characterize two-dimensional arrays of single molecule magnets within a wide range of temperatures and frequencies.

description: We introduce an approach to studying a driven qubit-oscillator system in the ultrastrong coupling regime, where the ratio $g/Ω$ between coupling strength and oscillator frequency approaches unity or goes beyond, and simultaneously for driving strengths much bigger than the qubit energy splitting (extreme driving). Both qubit-oscillator coupling and external driving lead to a dressing of the qubit tunneling matrix element of different nature: the former can be used to suppress selectively certain oscillator modes in the spectrum, while the latter can bring the qubit's dynamics to a standstill at short times (coherent destruction of tunneling) even in the case of ultrastrong coupling.

description: The link between aid and trade has been an important nexus in the global development framework since the World Trade Organization (WTO) launched its ‘aid for trade’ initiative at the 2005 Ministerial in Hong Kong. Proponents of Aid for Trade declared at the time that its purpose was to recognise the disadvantage of developing countries participating in the global trading system, and to bolster the effectiveness of aid disbursements. Yet Aid for Trade was also a creature of pragmatic politics. The trade community was motivated to give alms to the poor countries, which felt duped by the undelivered promises of the Doha Development Agenda. After the walkout in Cancun, aid for trade was a libation intended to induce developing countries back to the negotiating table. At the same time, the aid community was seeking a bulwark against growing criticism that development assistance was ineffective. By linking development aid with trade outcomes, donors and recipients could point to long-term poverty-reduction impacts of their projects. Seven years later, Aid for Trade has become a fixture in the development landscape, accounting for no less than 25 per cent of total official development aid (ODA) (OECD and WTO 2011). Aid for trade is being positioned as a building block in the future development agenda beyond the 2015 expiry of the Millennium Development Goals. This chapter analyses whether Aid for Trade has delivered on its promise. Has it delivered incremental resources to developing countries? Has it been a complement to pro-development liberalisation, unlocking genuine progress in multilateral trade reform? And has the focus on trade made aid more effective? As we show, considerable doubt remains on each of these questions. The Aid for Trade initiative may well be primarily a reallocation rather than an increase in assistance, and constitute a relabelling rather than a fundamental reform of the global trade and development framework. This chapter also considers alternative means to improve trade outcomes for developing countries. We propose that a ‘right to trade’ and a ‘right to development’ be enshrined within the WTO’s dispute settlement system. These rights would give developing countries increased opportunity within current and future trade agreements to expand their trade and safeguard their development. In addition, we propose that aid for trade funds should be consolidated into a more coherent and predictable framework. Dedicated funds should be committed by rich countries to a Global Trade Facility and dispersed through a transparent and competitive process. Together these proposals would go some way to creating a genuinely pro-development trade liberalisation agenda, giving developing countries greater scope to eliminate the international trade barriers and domestic capacity constraints that limit their ability to pursue export-led development pathways.
Influence of upstream solar wind on thermospheric flows at Jupiter

description: The coupling of Jupiter's magnetosphere and ionosphere plays a vital role in creating its auroral emissions. The strength of these emissions is dependent on the difference in speed of the rotational flows within Jupiter's high-latitude thermosphere and the planet's magnetodisc. Using an azimuthally symmetric global circulation model, we have simulated how upstream solar wind conditions affect the energy and direction of atmospheric flows. In order to simulate the effect of a varying dynamic pressure in the upstream solar wind, we calculated three magnetic field profiles representing compressed, averaged and expanded `middle' magnetospheres. These profiles were then used to solve for the angular velocity of plasma in the magnetosphere. This angular velocity determines the strength of currents flowing between the ionosphere and magnetosphere. We examine the influence of variability in this current system upon the global winds and energy inputs within the Jovian thermosphere. We find that the power dissipated by Joule heating and ion drag increases by ~190% and ~185% from our compressed to expanded model respectively. We investigated the effect of exterior boundary conditions on our models and found that by reducing the radial current at the outer edge of the magnetodisc, we also limit the thermosphere's ability to transmit angular momentum to this region.

Crises: Principles and Policies: With an Application to the Eurozone Crisis

description: Economies around the world have faced repeated crises — more frequently over the past thirty years. The fact that they have become more frequent and pervasive at the same time that we believe we have learned more about the management of the economy and as markets have seemingly improved poses a puzzle: shouldn't rational markets avoid these catastrophes, the costs of which outweigh, by an enormous amount, any benefit that might have accrued to the economy from the actions prior to the crisis that might have contributed to it? This is especially true of the large fraction of crises that can be called “debt crises,” precipitated by a country’s difficulty in repaying what it owes. The benefits of income smoothing (arising from the difference in the marginal utility of income in periods when income is low and when income is high) are overwhelmed by the social and economic costs of the ensuing crisis.
Flavor Violation in a Minimal SO(10)\times A_4 SUSY GUT

description: Flavor violating processes in the quark and lepton sectors are investigated within a realistic supersymmetric $SO(10)\times A_4$ grand unification model. By employing exotic heavy fermion fields, this model successfully describes various features of the fermion masses and mixings including large neutrino mixings accompanied by small quark mixings. In this model the flavor violation is induced at GUT scale, at which $A_4$ flavor symmetry is broken, as a consequence of the large mixings of the light fermion fields with these exotic heavy fields. The stringent experimental constraint from $μ\rightarrow eγ$ decay rate necessitates a high degree of degeneracy of the supersymmetry breaking soft scalar masses of the exotic heavy fields and supersymmetric scalar partners of the light fermion fields. The choice of slepton masses of order 1 TeV is found to be consistent with the constraints from branching ratio of $μ\rightarrow eγ$ and with all other flavor changing neutral current processes being sufficiently suppressed.

Exploration of croconic acid disodium salt as an organic battery electrode material
Creators: name: Chawla, Rupali
Publisher: name: No Publisher Supplied

description: We investigated croconic acid disodium salt for potential use as Li-ion battery material. The crystal was shown to be a promising electrode material with a medium to short battery cycle lifetime. We embarked in a thorough computational study based on classical molecular dynamics simulations to characterize this system and identify optimization strategies to improve battery lifetime. Through long-timescale molecular dynamics simulations in the Canonical Ensemble and Isothermal-Isobaric ensembles, we first established that the custom force field that we generated for this system reproduces the known thermodynamics of the Croconic acid disodium salt dihydrate crystal. In a second step, we predict the existence of a quasi-degenerate denser polymorph which is slightly less stable at room temperature and becomes more stable starting T=420K compared to the known crystal structure as determined by X-Ray crystallography. Interestingly, we find that upon adding lithium the system chooses the denser phase even at room temperature. Lithiation of the denser phase leads to moderate volume increases of about 0.75% for each additional 1% lithiation. By extrapolation of the results of the simulations, we conjecture that a phase transition takes place in the very first stages of lithiation. This should initially reduce the volume, resulting in the formation of cracks in the material contributing to a short battery cycle lifetime. We thus propose to assemble batteries based on croconate at an elevated temperature.

description: We study heavy light mesons in a QCD inspired quark model with the Cornell potential$-\frac{4α_{S}}{3r}+br+c$. Here we consider the linear term $br$ as the parent and $-\frac{4α_{S}}{3r}+c$ i.e.the Coloumbic part as the perturbation.The linear parent leads to Airy function as the unperturbed wavefunction. We then use the Dalgarno method of perturbation theory to obtain the total wavefunction corrected upto first order with Coulombic peice as the perturbation.With these wavefunctions, we study the Isgur-Wise function and calculate its slope and curvature.
