Year: 2016

description: Using shortcuts to adiabaticity, we solve the time-dependent Schroedinger equation that is reduced to a classical nonlinear integrable equation. For a given time-dependent Hamiltonian, the counterdiabatic term is introduced to prevent nonadiabatic transitions. Using the fact that the equation for the dynamical invariant is equivalent to the Lax equation in nonlinear integrable systems, we obtain the counterdiabatic term exactly. The counterdiabatic term is available when the corresponding Lax pair exists and the solvable systems are classified in a unified and systematic way. Multisoliton potentials obtained from the Korteweg-de Vries equation and isotropic XY spin chains from the Toda equations are studied in detail.

description: Motivated by quantum quenches in spin chains, a one-dimensional toy-model of fermionic particles evolving in imaginary-time from a domain-wall initial state is solved. The main interest of this toy-model is that it exhibits the arctic circle phenomenon, namely a spatial phase separation between a critically fluctuating region and a frozen region. Large-scale correlations inside the critical region are expressed in terms of correlators in a (euclidean) two-dimensional massless Dirac field theory. It is observed that this theory is inhomogenous: the metric is position-dependent, so it is in fact a Dirac field theory in curved space. The technique used to solve the toy-model is then extended to deal with the transfer matrices of other models: dimers on the honeycomb and square lattice, and the six-vertex model at the free fermion point ($Δ=0$). In all cases, explicit expressions are given for the long-range correlations in the critical region, as well as for the underlying Dirac action. Although the setup developed here is heavily based on fermionic observables, the results can be translated into the language of height configurations and of the gaussian free field, via bosonization. Correlations close to the phase boundary and the generic appearance of Airy processes in all these models are also briefly revisited in the appendix.

description: We propose a spectroscopic method to identify the nodal gap structure in unconventional superconductors. This method best suits for locating the horizontal line node and for pinpointing the isolated point nodes by measuring polar angle ($θ$) resolved zero energy density of states $N(θ)$. This is measured by specific heat or thermal conductivity at low temperatures under a magnetic field. We examine a variety of uniaxially symmetric nodal structure, including point and/or line nodes with linear and quadratic dispersions, by solving Eilenberger equation in vortex states. It is found that (A) the maxima of $N(θ)$ continuously shift from the anti-nodal to the nodal direction ($θ_{\rm n}$) as a field increases accompanying the oscillation pattern reversal at low and high fields. Furthermore, (B) local minima emerge next to $θ_{\rm n}$ on both sides except for the case of linear point node. These features are robust and detectable experimentally. Experimental results of $N(θ)$ performed on several superconductors, UPd$_2$Al$_3$, URu$_2$Si$_2$, Cu$_x$Bi$_2$Se$_3$, and UPt$_3$, are examined and commented in light of the present theory.

description: We explore Goldstone boson potentials in non-compact cosets of the form SO(n,1)/SO(n). We employ a geometric approach to find the scalar potential, and focus on the conditions under which it is compact in the large field limit. We show that such a potential is found for a specific misalignment of the vacuum. This result has applications in different contexts, such as in Composite Higgs scenarios and theories for the Early Universe. We work out an example of inflation based on a non-compact coset which makes predictions which are consistent with the current observational data.

description: Using graphical methods based on a `lookdown' and pruned version of the {\em ancestral selection graph}, we obtain a representation of the type distribution of the ancestor in a two-type Wright-Fisher population with mutation and selection, conditional on the overall type frequency in the old population. This extends results from Lenz, Kluth, Baake, and Wakolbinger (Theor. Pop. Biol., 103 (2015), 27-37) to the case of heavy-tailed offspring, directed by a reproduction measure $Λ$. The representation is in terms of the equilibrium tail probabilities of the line-counting process $L$ of the graph. We identify a strong pathwise Siegmund dual of $L$, and characterise the equilibrium tail probabilities of $L$ in terms of hitting probabilities of the dual process.

description: What happens when a continuously evolving stochastic process is interrupted with large changes at random intervals $τ$ distributed as a power-law $\sim τ^{-(1+α)};α>0$? Modeling the stochastic process by diffusion and the large changes as abrupt resets to the initial condition, we obtain {\em exact} closed-form expressions for both static and dynamic quantities, while accounting for strong correlations implied by a power-law. Our results show that the resulting dynamics exhibits a spectrum of rich long-time behavior, from an ever-spreading spatial distribution for $α< 1$, to one that is time independent for $α> 1$. The dynamics has strong consequences on the time to reach a distant target for the first time; we specifically show that there exists an optimal $α$ that minimizes the mean time to reach the target, thereby offering a step towards a viable strategy to locate targets in a crowded environment.

description: As part of the dynamics of marketing and communication, the practice of celebrity endorsement has seen an increasingly prolific development over the years alongside a new form of brand communication oriented to enhance brand/product perception through endorsements of authoritative celebrities. In more recent times, the advent of the video game medium, and in particular video games, has led brands to develop new promotional and communication methods from scratch or borrow from other mediums. One that is certainly evocative among those derived from other media fields is product placement. Among the practices developed from scratch, especially in recent years, it is possible to find the use of characters or elements from video games within brand communications. This study was developed to understand this new communication mode adopted in specific contexts by brands, the effects it has on the target audience and the economic and image returns. The contributions made to the matter by this study concern that part of marketing that is focused on the target audience's perception of the brand to develop a connection, a feeling and to boost sales. Moreover, being one of the first studies developed with qualitative methodology, it allows to observe a deeper level of perception from the target audience’s side. The study involved a sample of seven people from various parts of Italy, interviewed in a focus group to show how positive and relevant the impact of this form of communication is to the target audience and their impulse to purchase, in addition to the high level of brand awareness this methodology brings. Furthermore, during the focus group, it emerged that this practice could be a strong bridge between brands and gamers, by developing a solid feeling of inclusion in the target audience

description: Organisations are now aimed at achieving fast growth, continuous development, increased performance, profitability and being at the top of the global business spectrum. This necessitates the need for Management Control System (MCS) within firms which will improve firms’ competitiveness and performance. This study examines the impact of management control systems on organisational performance using belief control, boundary control, diagnostic control and interactive control systems as a proxy in the relationship between MCS and organisational performance. The study was anchored on Resource Based View (RBV) Theory and Contingency Theory. The study employed survey design which is a type of descriptive research design. Simple Random sampling technique was employed and relevant data were gathered through the use of structured questionnaire. The sample population consisted of three hundred and fifty-eight (358) employees of Globacom Limited, Lagos State. The findings revealed that all the management control system (belief, boundary, diagnostic, and interactive control systems) are directly related to organizational performance. The study recommends that managers should prioritize where to spend their time and resources when using management control systems.

description: Decision diagrams are an increasingly important tool in cutting-edge solvers for discrete optimization. However, the field of decision diagrams is relatively new, and is still incorporating the library of techniques that conventional solvers have had decades to build. We drew inspiration from the warm-start technique used in conventional solvers to address one of the major challenges faced by decision diagram based methods. Decision diagrams become more useful the wider they are allowed to be, but also become more costly to generate, especially with large numbers of variables. In the original version of this paper, we presented a method of peeling off a sub-graph of previously constructed diagrams and using it as the initial diagram for subsequent iterations that we call peel-and-bound. We tested the method on the sequence ordering problem, and our results indicate that our peel-and-bound scheme generates stronger bounds than a branch-and-bound scheme using the same propagators, and at significantly less computational cost. In this extended version of the paper, we also propose new methods for using relaxed decision diagrams to improve the solutions found using restricted decision diagrams, discuss the heuristic decisions involved with the parallelization of peel-and-bound, and discuss how peel-and-bound can be hyper-optimized for sequencing problems. Furthermore, we test the new methods on the sequence ordering problem and the traveling salesman problem with time-windows (TSPTW), and include an updated and generalized implementation of the algorithm capable of handling any discrete optimization problem. The new results show that peel-and-bound outperforms ddo (a decision diagram based branch-and-bound solver) on the TSPTW. We also close 15 open benchmark instances of the TSPTW.

description: Income- and price-elasticity of demand quantify the responsiveness of markets to changes in income, and in prices, respectively. Under the assumptions of utility maximization and preference-independence (additive preferences), mathematical relationships between income-elasticity values and uncompensated own and cross price-elasticity of demand are here derived for bundle of goods, using the differential approach to demand analysis. Key parameters are: the elasticity of the marginal utility of income, and the average budget-share. The proposed method can be applied to forecast the direct and indirect impact of price changes, and of financial instruments of policy using available estimates of the income elasticity of demand.

description: Zhanjiang and Shantou are big agricultural cities and important development poles of the East and West of the Guangdong Coastal Economic Belt. It is of great practical significance to quantitatively study the formation degree of development poles in economically underdeveloped regions. Taking Zhanjiang as an example, this paper constructs the development pole and measures the index by integrating 9 indicators, and analyzes the history and current situation of Zhanjiang as the development pole. It turns out that in the neighboring area, Zhanjiang has the ability to become a development pole, but it is far from being formed, and must cooperate with Haikou to form the dual development pole model. According to the analysis results, the corresponding suggestions are given in industry, ecology, transportation, talents, technological innovation and financial investment.
Spekulative Vernunft und die Möglichkeit befreiender Ver-änderung. Hegelianische Perspektiven
Creators: name: Schäfer, Gregor
Publisher: name: ——— Materialismo Storico ——— Rivista di filosofia, storia e scienze umane
Year: 2023

description: The present paper follows two main interests. Firstly, it argues for a critical understanding of freedom as involved in the complexity of an ongoing, per se conflictive, and contradictory process of liberation and qualitative change. Secondly, this understanding of freedom is brought together with its – systematic – foundations in Hegel’s conception of speculative idealism. As well as freedom hereby is critically articulated against dominant ideologies of freedom, Hegel’s speculative idealism is defended against dominant strands of receptions that reduce the complexity of the entire system. Whilst it is a common strategy of many influential receptions to separate Hegel’s philosophy of objective spirit – as the conception of politically-historically actualized freedom – from its speculative-logical framework and from absolute spirit as the system’s ultimate figure, the paper argues for the inherent connection between these two parts and, by doing so, for the emancipatory core of speculative reason. This setting implies that if, on the contrary, Hegel’s practical philosophy is separated from the speculative-logical framework and from absolute spirit, it loses its critical potential towards existing social-political conditions by being integrated into their hegemony (as expressed in dominant ideologies of freedom). In opposition to such a both hermeneutical and practical integration, the paper claims that speculative reason, by systematically articulating the world as a whole, makes visible, within the existing state of things, a crisis: an unsettling field of conflicts and struggles opening up the possibility of emancipation.

description: This essay aims to reconstruct the controversy between Trockij and the so-called french “democratic communists”, especially Simone Weil, in the early 1930s concerning the nature of the Soviet Union as a workers’ state. To this purpose, the theoretical exchanges and biographical contacts that took place between the two thinkers are collected and analysed, examining in particular their argument in the press on the topics of the October Revolution, the Bolshevik party, the political role of Stalin, bureaucracy in the USSR and the characteristics of the so-called “techno-bureaucratic” society. The latter is considered by Weil as a third form of state, distinct from both the advanced capitalist state and an ideal workers’ state, and identified by her with the Soviet Union under Stalin. Trockij rebuts Weil’s arguments in terms of method and content, attempting to define in Marxist terms what a workers’ state is or should be, and tracing Weil’s critique back to its Kantian matrix. Trockij; Simone Weil; Soviet Union; Revolution; Workers’ State; Marxism.

description: In this paper, we consider Einstein-Hilbert gravity in the presence of cosmological constant and an electric field of Yang-Mills type, which is minimally coupled to gravity. We couple the Ricci scalar to the Yang-Mills invariant to obtain a modified theory of gravity. The black brane solution of this model is introduced up to the first order of the $RF^{(a)}_{μα}F^{(a)μα} $ term. Then, the color non-abelian direct current (DC) conductivity and the ratio of shear viscosity to entropy density are calculated for this solution. Our results recover the Yang-Mills Schwarzschild AdS black brane in the limit of $q_2 \to 0$.

description: For decades, it has remained an open question, whether two dopants in the $t$--$J$ model bind in the strongly correlated regime of small spin couplings versus hopping, $J \ll t$. Here, we investigate this problem in Bethe lattice structures with Ising coupling $J_z$, and mainly focus on the case of a coordination number equal to 4. The special geometry circumvents subtle effects in regular lattices, but importantly still contains the non-trivial dependency on the rotational symmetry and particle statistics. It, furthermore, allows us to reach numerical convergence, and we conclusively answer whether binding occurs or not. In particular, we find that the rotationally symmetric $s$ waves unbind below $J_z \simeq 0.3 t$, which we unveil is tied to Pauli blocking of symmetrical hole configurations. This is further substantiated by the fact that holes in a bosonic spin environment shows strong -- superlinear -- binding at low $J_z / t$. Additionally, higher rotational fermionic $p$ and $d$ waves partially overcome the blocking, are perfectly degenerate, and bind for all $J_z / t$. In the strongly correlated regime of $J_z \ll t$, this binding occurs sublinearly with scaling $\sim t (J_z / t)^{3/2}$.

description: This study investigates two unavoidable noise factors: electronic noise and radiation scattering, associated with detectors and their electronics. This study proposes a novel methodology to estimate electronic and scattering noise separately. It utilizes mathematical tools, namely, Kanpur theorem-1, standard deviation, similarity dice coefficient parameters, and experimental Computerized Tomography technique. Four types of gamma detectors: CsI (Tl), LaBr_3 (Ce), NaI (Tl) and HPGe are used with their respective electronics. A detector having integrated circuit electronics is shown to impart significantly less (~33% less) electronic noise in data as compared to detectors with distributed electronics. Kanpur Theorem-1 signature is proposed as a scattering error estimate. An empirical expression is developed showing that scattering noise depends strongly on mass attenuation coefficients of detector crystal material and weakly on their active area. The difference between predicted and estimated relative scattering is 14.6%. The methodology presented in this study will assist the related industry in selecting the appropriate detector of optimal diameter, thickness, material composition, and hardware as per requirement.

For the conformally coupled scalar, an intricate phase diagram is charted out between the four relevant solutions: global AdS, boson star, Reissner-Nordstrom black hole and the hairy black hole. The nature of the phase diagram undergoes qualitative changes as the charge of the scalar is changed, which we discuss. We also discuss the new features that arise in the extremal limit.

description: The formation mechanism of AM CVn binary has not been well understood yet. Accurate measurements of the mass transfer rate can help to determine the formation mechanism. But unfortunately such observation by electromagnetic means is quite challenging. One possible formation channel of AM CVn binary is a semi-detached white dwarf binary. Such system emits strong gravitational wave radiation which could be measured by the future space-based detectors. We can simultaneously extract the mass transfer rate and the orbital period from the gravitational wave signal. We employ a post-Keplerian waveform model of gravitational wave and carry out a Fisher analysis to estimate the measurement accuracy of mass transfer rate through gravitational wave detection. Special attention is paid to the observed sources in Gaia Data Release 2. We found that we can accurately measure the mass transfer rate for those systems. Comparing to electromagnetic observations, gravitational wave detection improves the accuracy more than two orders of magnitude. Our results imply that the gravitational wave detection will help much in understanding the formation mechanism of AM CVn binaries.

description: We present a solution of sparse alternating current optimal power flow (ACOPF) analysis on graphical processing unit (GPU). In particular, we discuss the performance bottlenecks and detail our efforts to accelerate the linear solver, a core component of ACOPF that dominates the computational time. ACOPF analyses of two large-scale systems, synthetic Northeast (25,000 buses) and Eastern (70,000 buses) U.S. grids [1], on GPU show promising speed-up compared to analyses on central processing unit (CPU) using a state-of-the-art solver. To our knowledge, this is the first result demonstrating a significant acceleration of sparse ACOPF on GPUs.

description: We explore the explicit relationship between the descendant Gromov--Witten theory of target curves, operators on Fock spaces, and tropical curve counting. We prove a classical/tropical correspondence theorem for descendant invariants and give an algorithm that establishes a tropical Gromov--Witten/Hurwitz equivalence. Tropical curve counting is related to an algebra of operators on the Fock space by means of bosonification. In this manner, tropical geometry provides a convenient "graphical user interface" for Okounkov and Pandharipande's celebrated GW/H correspondence. An important goal of this paper is to spell out the connections between these various perspectives for target dimension 1, as a first step in studying the analogous relationship between logarithmic descendant theory, tropical curve counting, and Fock space formalisms in higher dimensions.

description: The Wigner-Smith time-delay of flux conserving systems is a real quantity that measures how long an excitation resides in an interaction region. The complex generalization of time-delay to non-Hermitian systems is still under development, and its statistical properties in the short-wavelength limit of complex chaotic scattering systems have not been investigated. From the experimentally measured multi-port scattering ($S$)-matrices of one-dimensional graphs, a two-dimensional billiard, and a three-dimensional cavity, we calculate the complex Wigner-Smith, as well as each individual reflection and transmission time-delays. The complex reflection time-delay differences between each port are calculated, and the transmission time-delay differences are introduced for systems exhibiting non-reciprocal scattering. Large time-delays are associated with scattering singularities such as coherent perfect absorption, reflectionless scattering, slow light, and uni-directional invisibility. We demonstrate that the large-delay tails of the distributions of the real and imaginary parts of each time-delay quantity are superuniversal, independent of experimental parameters: wave propagation dimension $\mathcal{D}$, number of scattering channels $M$, Dyson symmetry class $β$, and uniform attenuation $η$. The tails determine the abundance of the singularities in generic scattering systems, and the superuniversality is in direct contrast with the well-established statistics of unitary systems, where the distribution tail depends explicitly on the values of $M$ and $β$. We relate the statistics to the topological properties of the corresponding singularities. Although the results presented here are based on classical microwave experiments, they are applicable to any non-Hermitian wave-chaotic scattering system in the short-wavelength limit, such as optical or acoustic resonators.

description: We present a Mathematica package AmpRed for the semi-automatic calculations of multi-loop Feynman amplitudes with high efficiency and precision. AmpRed implements the methods of integration by parts and differential equations in the Feynman-parameter representation. It allows for the calculations of general parametric integrals (which may not have momentum-space correspondences). Various user-friendly tools for multi-loop calculations, such as those to construct and solve differential equations for Feynman integrals, are provided. It can also deal with tensor algebras in non-relativistic field theories. Interfaces to some packages, like QGRAF and FORM, are also provided.
