Quantum technologies are developing powerful tools to generate and manipulate
coherent superpositions of different energy levels. Envisaging a new generation
of energy-efficient quantum devices, here we explore how coherence can be
manipulated without exchanging energy with the surrounding environment. We
start from ... |
We give a new presentation of the Yangian for the orthosymplectic Lie
superalgebra $\mathfrak{osp}_{1|2m}$. It relies on the Gauss decomposition of
the generator matrix in the $R$-matrix presentation. The defining relations
between the Gaussian generators are derived from a new version of the
Drinfeld-type presentati... |
Spinor representation of group GL(4,R) on special spinor space is developed.
Representation space has a structure of the fiber space with the space of
diagonal metricses as the base and standard spinor space as typical fiber.
Non-isometric motions of the space-time entail spinor transformations which
are represente... |
After more than 30 years of validation of Moore's law, the CMOS technology
has already entered the nanoscale (sub-100nm) regime and faces strong
limitations. The nanowire transistor is one candidate which has the potential
to overcome the problems caused by short channel effects in SOI MOSFETs and has
gained signifi ... |
This paper presents inference rules for Resource Description Framework (RDF),
RDF Schema (RDFS) and Web Ontology Language (OWL). Our formalization is based
on Notation 3 Logic, which extended RDF by logical symbols and created Semantic
Web logic for deductive RDF graph stores. We also propose OWL-P that is a
lightwei... |
We discuss weighted estimates for the squares of the Riesz transforms, R^{2},
on L^{2}(W) where W is a matrix A2 weight. We prove that if W is close to the
Identity matrix Id, then the operator norm of R^{2} is close to its unweighted
norm on L^{2} which is one. This is done by the use of the Bellman function

Robust Gray codes were introduced by (Lolck and Pagh, SODA 2024). Informally,
a robust Gray code is a (binary) Gray code $\mathcal{G}$ so that, given a noisy
version of the encoding $\mathcal{G}(j)$ of an integer $j$, one can recover
$\hat{j}$ that is close to $j$ (with high probability over the noise). Such
codes ha... |
We study the dynamics of gyrotactic swimmers in turbulence, whose orientation
is governed by gravitational torque and local fluid velocity gradient. The
gyrotaxis strength is measured by the ratio of the Kolmogorov time scale to the
reorientation time scale due to gravity, and a large value of this ratio means
the gy... |
This paper describes how the non-gravitational contribution to Galactic
Velocity Rotation Curves can be explained in terms of a negative Cosmological
Constant ($\Lambda$). It will be shown that the Cosmological Constant leads to
a velocity contribution proportional to the radii, at large radii, and
depending on the m... |
The strong spectral order induces a natural partial ordering on the manifold
$H_{n}$ of monic hyperbolic polynomials of degree $n$. We prove that twisted
root maps associated with linear operators acting on $H_{n}$ are G\aa rding
convex on every polynomial pencil and we characterize the class of polynomial
pencils of... |
Neural Architecture Search (NAS) is a collection of methods to craft the way
neural networks are built. Current NAS methods are far from ab initio and
automatic, as they use manual backbone architectures or micro building blocks
(cells), which have had minor breakthroughs in performance compared to random
baselines. ... |
In manufacturing, the increasing involvement of autonomous robots in
production processes poses new challenges on the production management. In this
paper we report on the usage of Optimization Modulo Theories (OMT) to solve
certain multi-robot scheduling problems in this area. Whereas currently
existing methods are ... |
We study the spectrum of a quantum star graph with a non-selfadjoint Robin
condition at the central vertex. We first prove that, in the high frequency
limit, the spectrum of the Robin Laplacian is close to the usual spectrum
corresponding to the Kirchhoff condition. Then, we describe more precisely the
asymptotics of... |
Understanding body part geometry is crucial for precise medical diagnostics.
Curves effectively describe anatomical structures and are widely used in
medical imaging applications related to cardiovascular, respiratory, and
skeletal diseases. Traditional curve detection methods are often task-specific,
relying heavily... |
Despite decades of effort, the timing and duration of He II reionization, as
well as its morphology and the properties of the quasars believed to drive it,
are still not well constrained. In this paper we present a new method to study
both He II reionization and quasars via the thermal proximity effect -- the
photoel... |
Gravitational lensing deflects light. A single lens deflector can only shear
images, but cannot induce rotations. Multiple lens planes can induce rotations.
Such rotations can be observed in quadruply imaged sources, and can be used to
distinguish between two proposed solutions of the flux anomaly problem:

First-order, rhombohedral to orthorhombic, stress-induced phase transitions
have been evidenced by bulk charge-stress measurements and X-ray diffraction
derived lattice strain measurements in [001]c-poled PZN-4.5PT. The transitions
are induced by uniaxial, compressive loads applied either along or
perpendicular to th... |
We present results from the first simulations of networks of Type I Abelian
Higgs cosmic strings to include both matter and radiation eras and Cosmic
Microwave Background (CMB) constraints. In Type I strings, the string tension

mass-squared, $\beta$... |
In this article, we study the transport properties of
Graphene-Superconductor-Graphene (GSG) heterojunction where the superconducting

(SGS) type of Josephson junct... |
We show how to derive exact boundary $S$ matrices for integrable quantum
field theories in 1+1 dimensions using lattice regularization. We do this
calculation explicitly for the sine-Gordon model with fixed boundary conditions
using the Bethe ansatz for an XXZ-type spin chain in a boundary magnetic field.
Our results... |
There exist a number of models in the literature in which the weak
interactions are derived from a chiral gauge theory based on a larger group
than SU(2)_L x U(1)_Y. Such theories can be constructed so as to be
anomaly-free and consistent with precision electroweak measurements, and may be
interpreted as a deconstruc... |
The ability to manipulate clouds of ultra-cold atoms is crucial for modern
experiments on quantum manybody systems and quantum thermodynamics as well as
future metrological applications of Bose-Einstein condensate. While optical

We consider a branching random walk (BRW) taking its values in the
$\mathtt{b}$-ary rooted tree $\mathbb W_{ \mathtt{b}}$ (i.e. the set of finite
words written in the alphabet $\{ 1, \ldots, \mathtt{b} \}$, with $\mathtt{b}\!
\geq \! 2$). The BRW is indexed by a critical Galton--Watson tree conditioned
to have $n$ ve... |
We study the most general cosmological model with real scalar field which is
minimally coupled to gravity. Our calculations are based on
Friedmann-Lemaitre-Robertson-Walker (FLRW) background metric. Field equations
consist of three differential equations. We switch independent variable from
time to scale factor by ch... |
In this article, I provide significant mathematical evidence in support of
the existence of short-time approximations of any polynomial order for the
computation of density matrices of physical systems described by arbitrarily
smooth and bounded from below potentials. While for Theorem 2, which is
``experimental'', I... |
We consider time discretization methods for abstract parabolic problems with
inhomogeneous linear constraints. Prototype examples that fit into the general
framework are the heat equation with inhomogeneous (time dependent) Dirichlet
boundary conditions and the time dependent Stokes equation with an
inhomogeneous div... |
We formulate, using heuristic reasoning, precise conjectures for the range of
the number of primes in intervals of length $y$ around $x$, where $y\ll (\log
x)^2$. In particular we conjecture that the maximum grows surprisingly slowly
as $y$ ranges from $\log x$ to $(\log x)^2$. We will show that our conjectures
are s... |
We show that there are many compact subsets of the moduli space $M_g$ of
Riemann surfaces of genus $g$ that do not intersect any symmetry locus. This
has interesting implications for $\mathcal{N}=2$ supersymmetric conformal field
theories in four dimensions.

We study the anomalous Hall effect (AHE) in tilted Weyl metals with Gaussian
disorder due to the crossed X and {\Psi} diagrams in this work. The importance
of such diagrams to the AHE has been demonstrated recently in two dimensional
(2D) massive Dirac model and Rashba ferromagnets. It has been shown that the

We prove a new quantitative version of the Alexandrov theorem which states
that if the mean curvature of a regular set in R^{n+1} is close to a constant
in L^{n}-sense, then the set is close to a union of disjoint balls with respect
to the Hausdorff distance. This result is more general than the previous
quantificati... |
The accurate reconstruction of surgical scenes from surgical videos is
critical for various applications, including intraoperative navigation and

surgical scenes with... |
Soft, quasilocalized excitations (QLEs) are known to generically emerge in a
broad class of disordered solids, and to govern many facets of the physics of

We give a Littlewood-Richardson type rule for expanding the product of a
row-strict quasisymmetric Schur function and a symmetric Schur function in
terms of row-strict quasisymmetric Schur functions. This expansion follows from
several new properties of an insertion algorithm defined by Mason and Remmel
(2010) which ... |
We study the formation of spin-1 symbiotic spinor solitons in a quasi-one-
(quasi-1D) and quasi-two-dimensional (quasi-2D) hyper-fine spin $F=1$
ferromagnetic Bose-Einstein condensate (BEC). The symbiotic solitons
necessarily have a repulsive intraspecies interaction and are bound due to an
attractive interspecies in... |
Identifying the three-dimensional (3D) crystal-plane and strain-field
distributions of nanocrystals is essential for optical, catalytic, and
electronic applications. Here, we developed a methodology for visualizing the
3D information of chiral gold nanoparticles with concave gap structures by
Bragg coherent X-ray dif... |
The second quantization of the quaternionic fermionic field is undertaken
using the real Hilbert space approach to quaternionic quantum mechanics

quantum theory, and launches the basis to the development of the quaternionic
interaction theory.... |
We simulate the spin torque-induced reversal of the magnetization in thin
disks with perpendicular anisotropy at zero temperature. Disks typically
smaller than 20 nm in diameter exhibit coherent reversal. A domain wall is
involved in larger disks. We derive the critical diameter of this transition.
Using a proper def... |
This is a continuation of our recent paper. We continue studying properties
of the triangular projection ${\mathscr P}_n$ on the space of $n\times n$

In this paper, we develop a unified framework for analyzing the tracking
error and dynamic regret of inexact online optimization methods under a variety

2005]. The class ... |
As humans we possess an intuitive ability for navigation which we master
through years of practice; however existing approaches to model this trait for

research in the... |
The theory of scarring of eigenfunctions of classically chaotic systems by
short periodic orbits is extended in several ways. The influence of short-time

emphasized. We include the contribution to scarring of nonlinear recurrences
associated with ho... |
Let $\Sigma_g$ be a compact, connected, orientable surface of genus $g \geq
2$. We ask for a parametrization of the discrete, faithful, totally loxodromic
representations in the deformation space ${\rm Hom}(\pi_1(\Sigma_g), {\rm
SU}(3,1))/{\rm SU}(3,1)$. We show that such a representation, under some
hypothesis, can ... |
Individual species may experience diverse outcomes, from prosperity to

analyzed in two particul... |
This paper deals with the problem of predicting the future state of
discrete-time input-delayed systems in the presence of unknown disturbances

The ability to tune material properties using gate electric field is at the
heart of modern electronic technology. It is also a driving force behind recent

superconductivity and metal-insulator transition. Here we describe an ionic
field-effect ... |
With $\mu\to e\gamma$ decay forbidden by multiplicative lepton number
conservation, we study muonium--antimuonium transitions induced by neutral

while for singlet muonium, pseudoscalar and scalar contributions add
constructively. This is in co... |
The geometric approach to study the dynamics of U(1)-invariant membranes is

Although the Large Hadron Collider (LHC) has not observed supersymmetric
(SUSY) partners of the Standard Model particles, their existence is not ruled

quark. I... |

To confirm this theoretical prediction, we cultivated tumorspheres enriched in
CSCs, a... |
Interferometric principles are widely used in precision physics experiments

Electronic devices using epitaxial graphene on Silicon Carbide require
encapsulation to avoid uncontrolled doping by impurities deposited in ambient

We study a quasi-static evolution of thermo-visco-elastic model. We act with
external forces on non-homogeneous material body, which is a subject of our

Dirac equation w... |
In many physical systems it is important to be aware of the crossings and

The isospin mass splittings of the pseudoscalar and vector D and B
light-heavy quark system have been calculated using the method of QCD sum
