The Wigner function of the compass state (a superposition of four coherent
states) develops phase-space structures of dimension much less than the Planck
scale, which are crucial in determining the sensitivity of these states to
phase-space displacements. In the present work, we introduce compass-like
states that may h... | http://arxiv.org/abs/2301.00195v2 |
Fuzzy relational inequalities with fuzzy constraints (FRI-FC) are the
generalized form of fuzzy relational inequalities (FRI) in which fuzzy
inequality replaces ordinary inequality in the constraints. Fuzzy constraints
enable us to attain optimal points (called super-optima) that are better
solutions than those resulte... | http://arxiv.org/abs/2309.05624v1 |
Motivated by applications in queueing theory, we consider a stochastic
control problem whose state space is the $d$-dimensional positive orthant. The
controlled process $Z$ evolves as a reflected Brownian motion whose covariance
matrix is exogenously specified, as are its directions of reflection from the
orthant's bou... | http://arxiv.org/abs/2309.11651v4 |
We propose an extended compass model that hosts subsystem symmetries and has
potential experimental relevance with 3d transition metal compounds. The
subsystem symmetries strongly constrain the mobility of spin excitations and
lead to profound consequences. At the quantum critical point we find the
presence of "critica... | http://arxiv.org/abs/2309.08300v3 |
Long Term Evolution (LTE) signal is ubiquitously present in electromagnetic
(EM) background environment, which make it an attractive signal source for the
ambient backscatter communications (AmBC). In this paper, we propose a system,
in which a backscatter device (BD) introduces artificial Doppler shift to the
channel ... | http://arxiv.org/abs/2301.13664v1 |
This review is the first step in a long-term research project exploring how
social robotics and AI-generated content can contribute to the creative
experiences of older adults, with a focus on collaborative drawing and
painting. We systematically searched and selected literature on human-robot
co-creativity, and analyz... | http://arxiv.org/abs/2309.07033v2 |
In the rapidly evolving digital era, the analysis of document layouts plays a
pivotal role in automated information extraction and interpretation. In our
work, we have trained MViTv2 transformer model architecture with cascaded mask
R-CNN on BaDLAD dataset to extract text box, paragraphs, images and tables from
a docum... | http://arxiv.org/abs/2308.16571v1 |
We investigate the CP violation in the decay process $\bar B_{s} \rightarrow
\phi(\rho,\omega) P \rightarrow K^{+}K^{-}P$ by considering the interference
effects of $\phi\rightarrow K^{+}K^{-}$, $\rho\rightarrow K^{+}K^{-}$ and
$\omega\rightarrow K^{+}K^{-}$ within the framework of perturbative QCD method
(P refers to ... | http://arxiv.org/abs/2309.15351v1 |
Quantum mechanics, superfluids, and capillary fluids are closely related: it
is thermodynamics that links them. In this paper, the Liu procedure is used to
analyze the thermodynamic requirements. A comparison with the traditional
method of divergence separation highlights the role of spacetime. It is shown
that perfect... | http://arxiv.org/abs/2301.07177v2 |
Quantum computing has gained attention in recent years due to the significant
progress in quantum computing technology. Today many companies like IBM, Google
and Microsoft have developed quantum computers and simulators for research and
commercial use. The development of quantum techniques and algorithms is
essential t... | http://arxiv.org/abs/2303.00075v2 |
The design and optimization of a large-scale fault-tolerant quantum computer
architecture relies extensively on numerical simulations to assess the
performance of each component of the architecture. The simulation of
fault-tolerant gadgets, which are typically implemented by Clifford circuits,
is done by sampling circu... | http://arxiv.org/abs/2309.15345v1 |
Stance classification, the task of predicting the viewpoint of an author on a
subject of interest, has long been a focal point of research in domains ranging
from social science to machine learning. Current stance detection methods rely
predominantly on manual annotation of sentences, followed by training a
supervised ... | http://arxiv.org/abs/2309.13734v2 |
Collisions are an important dissipation mechanism in plasmas. In
one-dimensional modelling, a commonly used collision operator is the
Lenard-Bernstein operator, or its modified energy- and momentum-conserving
counterpart. When approximating such operators numerically, it is important to
respect their structure in order... | http://arxiv.org/abs/2309.16894v2 |
Gamma-Ray Bursts are the most luminous events in the Universe, and are
excellent laboratories to study extreme physical phenomena in the cosmos.
Despite a long trajectory of progress in understanding these highly energetic
events, there are still many observed features that are yet to be fully
explained. Observations o... | http://arxiv.org/abs/2309.07999v2 |
