Unimodular Einstein--Cartan gravity: Dynamics and conservation laws

description: Unimodular gravity is an interesting approach to address the cosmological constant problem, since the vacuum energy density of quantum fields does not gravitate in this framework, and the cosmological constant appears as an integration constant. These features arise as a consequence of considering a constrained volume element 4-form that breaks the diffeomorphisms invariance down to volume preserving diffeomorphisms. In this work, the first-order formulation of unimodular gravity is presented by considering the spin density of matter fields as a source of spacetime torsion. Even though the most general matter Lagrangian allowed by the symmetries is considered, dynamical restrictions arise on their functional dependence. The field equations are obtained and the conservation laws associated with the symmetries are derived. It is found that, analogous to torsion-free unimodular gravity, the field equation for the vierbein is traceless; nevertheless, torsion is algebraically related to the spin density as in standard Einstein-Cartan theory. The particular example of massless Dirac spinors is studied, and comparisons with standard Einstein-Cartan theory are shown.

Multi-Channel Kondo Necklace

subject: FOS: Physical sciences

description: A multi--channel generalization of Doniach's Kondo necklace model is formulated, and its phase diagram studied in the mean--field approximation. Our intention is to introduce the possible simplest model which displays some of the features expected from the overscreened Kondo lattice. The $N$ conduction electron channels are represented by $N$ sets of pseudospins $\vt_{j}$, $j=1, ... , N$, which are all antiferromagnetically coupled to a periodic array of $|\vs|=1/2$ spins. Exploiting permutation symmetry in the channel index $j$ allows us to write down the self--consistency equation for general $N$. For $N>2$, we find that the critical temperature is rising with increasing Kondo interaction; we interpret this effect by pointing out that the Kondo coupling creates the composite pseudospin objects which undergo an ordering transition. The relevance of our findings to the underlying fermionic multi--channel problem is discussed.

It is observed that this coupling is small in the vector channel for all $T>T_c$, but not in the pseudoscalar channel. The temperature dependence of hadronic parameters below \tc{} is found to be small. NOTE: Latex source, no figures, needs espcrc2.sty from hep-lat macros.

description: The aims of this paper are twofold. First, to investigate the accuracy of different option-implied trees in pricing European options in order to assess the power of implied trees in replicating the market information. Second, to compare deterministic volatility implied trees and stochastic implied volatility models (Bakshi et al. (2003)) in assessing the forecasting power of implied moments on subsequently realised moments, and ascertaining the existence, magnitude and sign of variance, skewness, and kurtosis risk-premia. The analysis is carried out using the Italian daily market data covering the period 2005-2014. This enables us to contrast the pricing performance of implied trees and to assess the magnitude and sign of risk premia in both a tranquil and a turmoil period. The findings are as follows. First, the pricing performance of the Enhanced Derman and Kani (EDK, Moriggia et al. 2009) model is superior to that of the Rubinstein (1994) model. This superiority is stronger especially in the high volatility period due to a better estimation of the left tail of the distribution describing bad market conditions. Second, the Bakshi et al. (2003) formula is the most accurate for forecasting skewness and kurtosis, while for variance it yields upwardly biased forecasts. All models agree on the signs of the risk premia: negative for variance and kurtosis, and positive for skewness, but differ in magnitude. Overall, the results suggest that selling (buying) variance and kurtosis (skewness) is profitable in both high and low volatility periods.

description: Geometri is one of branch of the branch of mathematics that plays a major role in the development of science and technology. Thus, knowing the geometry concept is needed for students from their early basic level of thinking. A preliminary study showed that the elementary students have difficulty in perceiving parallelogram shape in a 2-dimension of a cube drawing as a square shape. This difficulty makes the students can not solve geometrical problems correctly. This problem is related to the internal thinking process in geometry. We conducted the exploration of students internal thinking processes in geometry particularly in distinguishing the square and parallelogram shape. How the students process their internal thinking through distortion and abstraction is the main aim of this study. Analysis of geometrical test and deep interview are used in this study to obtain the data, The result of this study is there are two types of distortion and abstraction respectively in which the student used in their internal thinking processes.
Design of trustable eFuses for automotive E/E architectures

description: Electric vehicles are equipped with a complex network of electronics that operate at high currents and voltages. Protecting the vehicle's electrical system from damage caused by overcurrent and overtemperature is a crucial design requirement. Short circuits can have serious consequences, including potential fatalities. Therefore, all components within the E/E architecture must be safeguarded against hazardous conditions such as overvoltage, undervoltage, overcurrent, and overtemperature. At the same time, reducing the vehicle's weight and cost while increasing the battery range requires to minimize cable harness cross-sections. To achieve both goals, new devices like smart fuses are utilized, enabling more flexible and intelligent protection schemes. However, the increased functionality of smart fuses also brings about challenges in designing and verifying their performance, particularly under dynamically-changing load conditions. In this study, we propose a simulation-based verification methodology for overtemperature protection algorithms in automotive smart fuses. Our approach involves a co-simulation between the mixed-signal fuse and a thermal reduced-order model of the relevant part of the E/E architecture, using SystemC AMS. While the virtual Electronic Control Unit executes the target executable, the analog and thermal domains are simulated concurrently. The electrothermal model can be integrated into a Virtual Platform, facilitating a Software-on-Top workflow and the analysis of algorithms under complex, dynamically-changing currents.

description: Atomistic simulations using an EAM potential are carried out to investigate the first stages of plasticity in aluminum slabs, in particular the effect of both temperature and step geometry on the nucleation of dislocations from surface steps. Temperature is shown to significantly reduce the elastic limit, and to activate the nucleation of dislocation half-loops. Twinning occurs by successive nucleations in adjacent glide planes. The presence of a kinked step is shown to have no influence on the nucleation mechanisms.

Our approach addresses an outstanding issue in the phase diagram of the skyrmion host FeGe by showing that dc magnetic anomalies can be explained in terms of entropic signatures consistent with a phase diagram containing a single pocket of skyrmionic order and a Brazovskii transition.

Interface Depinning in a Disordered Medium - Numerical Results
Creators: name: Leschhorn, Heiko
Publisher: name: arXiv
Year: 1993
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We propose a lattice model to study the dynamics of a driven interface in a medium with random pinning forces. For driving forces F smaller than a threshold force F_c the whole interface gets pinned. The depinning transition can be characterized by a set of critical exponents: the static and dynamical roughness exponent, the velocity exponent defined by the scaling of the velocity of the interface with F-F_c, and a correlation length exponent. The critical exponents are determined numerically in 1+1 and 2+1 dimensions. Our findings are compared with recent numerical and analytical results for a Langevin equation with quenched noise, which is expected to be in the same universality class. Our results support a recent functional renormalization group calculation by T.Nattermann et.al. (J.Phys.II France 2, 1483 (1992)).

Lo stress lavoro-correlato: dalla valutazione alle misure organizzative di prevenzione

description: Questo breve saggio � dedicato all?illustrazione di un approccio allo stress lavoro-correlato che supera i limiti della prassi prevalente e ristabilisce la centralit� dell?organizzazione del lavoro nell?eziologia e conseguentemente nella prevenzione dello stress lavoro-correlato.
Secondo gli orientamenti normativi e giurisprudenziali in materia, gli obblighi datoriali di prevenzione sono innanzitutto primari; la valutazione cio� deve essere innanzitutto finalizzata alla diagnosi e all?intervento sulle caratteristiche organizzative della situazione di lavoro che influiscono sull?insorgenza dello stress. Il saggio argomenta che la scelta degli strumenti e delle modalit� di valutazione impatta in maniera decisiva sulla capacit� di ottemperare a tale obbligo. Gli strumenti e le prassi di valutazione oggi pi� diffusi hanno certamente una valenza diagnostica della presenza di un problema di stress lavoro-correlato e forniscono informazioni utili a orientare la ricerca delle soluzioni; essi, tuttavia, non bastano per risalire alle cause organizzative dei problemi rilevati, e quindi per individuare quale sia lo specifico intervento organizzativo da realizzare in concreto in quanto adeguato alla prevenzione del problema. Nell?intento di contribuire a colmare questo gap, il saggio propone e illustra un approccio alla valutazione dello stress lavoro-correlato interdisciplinare e mixed-method, che combina in modo razionale ed efficiente indicatori oggettivi e soggettivi, analisi organizzativa (propriamente detta) e intervento nelle situazioni di lavoro stressogene (eventualmente) identificate. In questo approccio la valutazione dei rischi e la diagnosi dei problemi non sono separate dalla individuazione delle scelte organizzative che possono averli generati, e dalla progettazione delle conseguenti misure di prevenzione.

description: Die Hochland-Tiefland Beziehungen in den Gebirgen der Welt betrachten wir in einer historischen Perspektive. Als zentrales Element erkennen wir die Mobilität von Menschen, Gütern und Kapital, die den zeitbedingten Kraftlinien unterschiedlicher Interessen zwischen oben und unten folgten. Wir stellen diese Beziehungen dann in den Rahmen der wissenschaftlichen, politischen und zivilgesellschaftlichen Diskurse, die insbesondere seit der UNO Konferenz in Rio 1992 die Wahrnehmung und Bewertung der Gebirgsräume im globalen und regionalen Maßstab signifikant verändert haben. Ein neues partnerschaftliches Verständnis hat sich seither herausgebildet, dem wir in ausgewählten Institutionen zur Stärkung der Position der Gebirgsräume nachgehen. Noch fehlt in vielen dieser Arrangements die Begegnung auf Augenhöhe, die wir als Voraussetzung einer nachhaltigen Entwicklungsstrategie betrachten. Highland-lowland relationships and their importance for sustainable development in mountain regions: This study takes a historical perspective of highland-lowland relationships in the mountains of the world. Central to this perspective is the mobility of people, goods, and capital, which follow temporal constellations of power between the different interests at high and low altitudes. We place these relationships within the framework of scientific, political, and civil-society discourses, which have significantly changed the perception and assessment of mountain areas on a global and regional scale – particularly since the Rio Earth Summit of 1992. A new, partnership-based understanding has emerged, but to what extent is it being implemented in institutions created to strengthen the position of mountain areas? Our findings show that many of these arrangements are still missing what we consider a prerequisite for a sustainable development strategy: encounters that take place on an equal footing.

description: Employing a new experimental technique to measure magnetoelectric response functions, we have measured the magnetoelectric effect in composite films of nano granular metallic iron in anatase titanium dioxide at temperatures below 50 K. A magnetoelectric resistance is defined as the ratio of a transverse voltage to bias current as a function of the magnetic field. In contrast to the anomalous Hall resistance measured above 50 K, the magnetoelectic resistance below 50 K is significantly larger and exhibits an even symmetry with respect to magnetic field reversal $H\to -H$. The measurement technique required attached electrodes in the plane of the film composite in order to measure voltage as a function of bias current and external magnetic field. To our knowledge, the composite films are unique in terms of showing magnetoelectric effects at low temperatures, $$ 50 K.

description: Successful materials innovations can transform society. However, materials research often involves long timelines and low success probabilities, dissuading investors who have expectations of shorter times from bench to business. A combination of emergent technologies could accelerate the pace of novel materials development by 10x or more, aligning the timelines of stakeholders (investors and researchers), markets, and the environment, while increasing return-on-investment. First, tool automation enables rapid experimental testing of candidate materials. Second, high-throughput computing (HPC) concentrates experimental bandwidth on promising compounds by predicting and inferring bulk, interface, and defect-related properties. Third, machine learning connects the former two, where experimental outputs automatically refine theory and help define next experiments. We describe state-of-the-art attempts to realize this vision and identify resource gaps. We posit that over the coming decade, this combination of tools will transform the way we perform materials research. There are considerable first-mover advantages at stake, especially for grand challenges in energy and related fields, including computing, healthcare, urbanization, water, food, and the environment.

description: In the quenched approximation, loops of the light singlet meson (the $η'$) give rise to a type of chiral logarithm absent in full QCD. These logarithms are singular in the chiral limit throwing doubt upon the utility of the quenched approximation. In previous work, I summed a class of diagrams, leading to non-analytic power dependencies such as $\cond\propto m_q^{-δ/(1+δ)}$. I suggested, however, that these peculiar results could be redefined away. Here I give an alternative derivation of the results, based on the renormalization group, and argue that they cannot be redefined away. I discuss the evidence (or lack thereof) for such effects in numerical data.

description: We present a method for computing resonant inelastic x-ray scattering (RIXS) spectra in one-dimensional systems using the density matrix renormalization group (DMRG) method. By using DMRG to address the problem, we shift the computational bottleneck from the memory requirements associated with exact diagonalization (ED) calculations to the computational time associated with the DMRG algorithm. This approach is then used to obtain RIXS spectra on cluster sizes well beyond state-of-the-art ED techniques. Using this new procedure, we compute the low-energy magnetic excitations observed in Cu $L$-edge RIXS for the challenging corner shared CuO$_4$ chains, both for large multi-orbital clusters and downfolded $t$-$J$ chains. We are able to directly compare results obtained from both models defined in clusters with identical momentum resolution. In the strong coupling limit, we find that the downfolded $t$-$J$ model captures the features of the magnetic excitations probed by RIXS after a uniform scaling of the spectra is taken into account.

description: We apply some methods of homology and K-theory to special classes of branes wrapping homologically nontrivial cycles. We treat the classification of four-geometries in terms of compact stabilizers (by analogy with Thurston's classification of three-geometries) and derive the K-amenability of Lie groups associated with locally symmetric spaces listed in this case. More complicated examples of T-duality and topology change from fluxes are also considered. We analyse D-branes and fluxes in type II string theory on ${\mathbb C}P^3\times Σ_g \times {\mathbb T}^2$ with torsion $H-$flux and demonstrate in details the conjectured T-duality to ${\mathbb R}P^7\times X^3$ with no flux. In the simple case of $X^3 = {\mathbb T}^3$, T-dualizing the circles reduces to duality between ${\mathbb C}P^3\times {\mathbb T}^2 \times {\mathbb T}^2$ with $H-$flux and ${\mathbb R}P^7\times {\mathbb T}^3$ with no flux.

description: This thesis consists of three chapters, in which I study the role of globalization and how political views are formed. The first chapter studies the rise of backlash against tourism as a form of antiglobalization sentiment, looking at the role of Airbnb. I construct a spatially disaggregated dataset to study the consequences of Airbnb in London. First, I document that 1 additional Airbnb tourist per 1000 residents increases complaints against tourists by 2.2 per cent. Secondly, I explore the roots of these reactions. I find that higher Airbnb penetration decreases neighbourhood quality, while the housing market is marginally affected. These negative externalities can be explained by a lack of monitoring and coordination by hosts, which are key differences compared to traditional hotel accommodations. Finally, I show that the deterioration of neighbourhood quality markedly reduces social capital, and worsens attitudes towards globalization, with higher support for Brexit. The second chapter documents how firms in tradable sectors are more likely to be subject to external competition to limit market power while non-tradable firms are more dependent on domestic policies and institutions. We combine an antitrust index with firm-level data from Orbis covering more than 12 million firms from 94 countries and find that profit margins of firms operating in non-tradable sectors are significantly lower in countries with stronger antitrust policies. The third chapter studies the impact of the Italian civil war and Nazi occupation of Italy in 1943– 45 on postwar political outcomes. The Communist Party, more active in the resistance movement, gained votes in areas where the Nazi occupation was both longer and harsher, mainly at the expense of centrist parties. This effect persists until the late 1980s. These results suggest that civil war and widespread political violence reshaped political identities in favour of the political groups that emerge as winners.

description: We present the analysis of the first two years of the OGLE search for gravitational lenses towards the Galactic bulge. We detected 9 microlensing events in an algorithmic search of $ \sim 10^8 $ measurements of $ \sim 10^6 $ stars. The characteristic time scales are in the range $ 8.6 < t_0 < 62 $ days, where $ t_0 = R_E / V $. The distribution of amplitudes is consistent with theoretical expectation. The stars seem to be drawn at random from the overall distribution of the observed bulge stars. We find that the optical depth to microlensing is larger than $ ( 3.3 \pm 1.2 ) \times 10^{-6}$, in excess of current theoretical estimates.

Brane SUSY Breaking and the Gravitino Mass

description: Supergravity models with spontaneously broken supersymmetry have been widely investigated over the years, together with some notable non-linear limits. Although in these models the gravitino becomes naturally massive absorbing the degrees of freedom of a Nambu-Goldstone fermion, there are cases in which the naive counting of degrees of freedom does not apply, in particular because of the absence of explicit gravitino mass terms in unitary gauge. The corresponding models require non-trivial de Sitter-like backgrounds, and it becomes of interest to clarify the fate of their Nambu-Goldstone modes. We elaborate on the fact that these non-trivial backgrounds can accommodate, consistently, gravitino fields carrying a number of degrees of freedom that is intermediate between those of massless and massive fields in a flat spacetime. For instance, in a simple supergravity model of this type with de Sitter background, the overall degrees of freedom of gravitino are as many as for a massive spin-3/2 field in flat spacetime, while the gravitino remains massless in the sense that it undergoes null-cone propagation in the stereographic picture. On the other hand, in the ten-dimensional USp(32) Type I Sugimoto model with "brane SUSY breaking", which requires a more complicated background, the degrees of freedom of gravitino are half as many of those of a massive one, and yet it somehow behaves again as a massless one.

description: We show an explicit formula, with a quite easy deduction, for the exponential matrix $e^{tA}$ of a real square matrix $A$ of order $n\times n$. The elementary method developed requires neither Jordan canonical form, nor eigenvectors, nor resolution of linear systems of differential equations, nor resolution of linear systems with constant coefficients, nor matrix inversion, nor complex integration, nor functional analysis. The basic tools are power series and the method of partial fraction decomposition. Two examples are given. A proof of one well-known stability result is given.

Anyon Mean Field as an Exact Limit of a Gauge Theory

description: We summarize a study of an Abelian gauge theory in 2+1 dimensions, the gauge field being coupled to nonrelativistic Fermions. The Action for the gauge field is a combination of the Maxwell term and a Chern-Simons (CS) term. We study the limit of vanishing Fermions' charge, keeping fixed the gauge field mass induced by the CS term. By considering a closed surface, in particular a torus to keep translational invariance, we show that the Fermions do not decouple completely from the gauge field, and in fact they behave as Anyons treated in the -translationally invariant formulation of the- Mean Field approximation. We describe the exact solution of this limiting case.

description: We present the characterization of a laser frequency stabilization scheme using a state-of-the-art wavelength meter based on solid Fizeau interferometers. For a frequency-doubled Ti-sapphire laser operated at 461 nm, an absolute Allan deviation below $10^{-9}$ with a standard deviation of $1$ MHz over 10\,h is achieved. Using this laser for cooling and trapping of strontium atoms, the wavemeter scheme provides excellent stability in single-channel operation. Multi-channel operation with a multimode fiber switch results in fluctuations of the atomic fluorescence correlated to residual frequency excursions of the laser. The wavemeter-based frequency stabilization scheme can be applied to a wide range of atoms and molecules for laser spectroscopy, cooling and trapping.
