Repulsive Fermi polarons with negative effective mass | Recent LENS experiment on a 3D Fermi gas has reported a negative effective
mass ($m^*<0$) of Fermi polarons in the strongly repulsive regime. There
naturally arise a question whether the negative $m^*$ is a precursor of the
instability towards phase separation (or itinerant ferromagnetism). In this
work, we make use ... | 0 | 1 | 0 | 0 | 0 | 0 |
Entropy Formula for Random $\mathbb{Z}^k$-actions | In this paper, entropies, including measure-theoretic entropy and topological
entropy, are considered for random $\mathbb{Z}^k$-actions which are generated
by random compositions of the generators of $\mathbb{Z}^k$-actions. Applying
Pesin's theory for commutative diffeomorphisms we obtain a measure-theoretic

Kohn anomalies in momentum dependence of magnetic susceptibility of some three-dimensional systems | We study a question of presence of Kohn points, yielding at low temperatures
non-analytic momentum dependence of magnetic susceptibility near its maximum,

nearest and ... | 0 | 1 | 0 | 0 | 0 | 0 |
Stability conditions, $τ$-tilting Theory and Maximal Green Sequences | Extending the notion of maximal green sequences to an abelian category, we
characterize the stability functions, as defined by Rudakov, that induce a
maximal green sequence in an abelian length category. Furthermore, we use
$\tau$-tilting theory to give a description of the wall and chamber structure
of any finite di... | 0 | 0 | 1 | 0 | 0 | 0 |
The thermal phase curve offset on tidally- and non-tidally-locked exoplanets: A shallow water model | Using a shallow water model with time-dependent forcing we show that the peak
of an exoplanet thermal phase curve is, in general, offset from secondary
eclipse when the planet is rotating. That is, the planetary hot-spot is offset
from the point of maximal heating (the substellar point) and may lead or lag

On Asymptotic Standard Normality of the Two Sample Pivot | The asymptotic solution to the problem of comparing the means of two

happen if the ... | 0 | 0 | 1 | 1 | 0 | 0 |
Breakthrough revisited: investigating the requirements for growth of dust beyond the bouncing barrier | For grain growth to proceed effectively and lead to planet formation a number
of barriers to growth must be overcome. One such barrier, relevant for compact
grains in the inner regions of the disc, is the `bouncing barrier' in which
large grains ($\sim$ mm size) tend to bounce off each other rather than
sticking. How... | 0 | 1 | 0 | 0 | 0 | 0 |
Extremely high magnetoresistance and conductivity in the type-II Weyl semimetals WP2 and MoP2 | The peculiar band structure of semimetals exhibiting Dirac and Weyl crossings
can lead to spectacular electronic properties such as large mobilities
accompanied by extremely high magnetoresistance. In particular, two closely
neighbouring Weyl points of the same chirality are protected from annihilation

Density and current profiles in $U_q(A^{(1)}_2)$ zero range process | The stochastic $R$ matrix for $U_q(A^{(1)}_n)$ introduced recently gives rise
to an integrable zero range process of $n$ classes of particles in one

fixed as defects influence the grand canonical ensemble of the second class
particles. By usi... | 0 | 1 | 0 | 0 | 0 | 0 |
Crystal structure, site selectivity, and electronic structure of layered chalcogenide LaOBiPbS3 | We have investigated the crystal structure of LaOBiPbS3 using neutron
diffraction and synchrotron X-ray diffraction. From structural refinements, we
found that the two metal sites, occupied by Bi and Pb, were differently
surrounded by the sulfur atoms. Calculated bond valence sum suggested that one
metal site was nea... | 0 | 1 | 0 | 0 | 0 | 0 |
Responses of Pre-transitional Materials with Stress-Generating Defects to External Stimuli: Superelasticity, Supermagnetostriction, Invar and Elinvar Effects | We considered a generic case of pre-transitional materials with static

temperatures close but above the starting temperature of martensitic
transformation, Ms. Using the Phase Field Microelasticity theory and 3D
simulation, we demonstrated tha... | 0 | 1 | 0 | 0 | 0 | 0 |
On The Robustness of Epsilon Skew Extension for Burr III Distribution on Real Line | The Burr III distribution is used in a wide variety of fields of lifetime

on the positive axis and has two shape parameters, say $c$ and $k$. These shape
parameters make the distribution quite flexible. They also control the tail

Logics for Word Transductions with Synthesis | We introduce a logic, called LT, to express properties of transductions, i.e.
binary relations from input to output (finite) words. In LT, the input/output
dependencies are modelled via an origin function which associates to any
position of the output word, the input position from which it originates. LT is

Topology and strong four fermion interactions in four dimensions | We study massless fermions interacting through a particular four fermion term

Augmentor: An Image Augmentation Library for Machine Learning | The generation of artificial data based on existing observations, known as

Multilevel Sequential${}^2$ Monte Carlo for Bayesian Inverse Problems | The identification of parameters in mathematical models using noisy

Multiparameter actuation of a neutrally-stable shell: a flexible gear-less motor | We have designed and tested experimentally a morphing structure consisting of

Latent Estimation of GDP, GDP per capita, and Population from Historic and Contemporary Sources | The concepts of Gross Domestic Product (GDP), GDP per capita, and population
