The anomalous Hall effect (AHE) is a quantum coherent transport phenomenon

Friedmann equations, we provide a qualitative description of the dynamics of
anisotropy perturbations. We find that the spacetime stability depends on the
sign of the ... | http://arxiv.org/abs/2301.06616v1 |
The Fast Multipole Method (FMM) for the Poisson equation is extended to the
case of non-axisymmetric problems in an axisymmetric domain, described by
cylindrical coordinates. The method is based on a Fourier decomposition of the
source into a modal expansion and the evaluation of the corresponding modes of
the field us... | http://arxiv.org/abs/2301.01179v1 |
In this paper we study quantum field theory in impulsive plane wave
spacetimes. We first analyze the geodesics and the formation of conjugate
planes in these spacetimes. The behaviors of the world function and the van
Vleck determinant near conjugate plane are also considered. For the quantum
field, we work out the mod... | http://arxiv.org/abs/2309.02252v1 |
Linearizability has been the long standing gold standard for consistency in
concurrent data structures. However, proofs of linearizability can be long and
intricate, hard to produce, and extremely time consuming even to verify. In
this work, we address this issue by introducing simple $universal$, $sound$,
and $complet... | http://arxiv.org/abs/2302.00737v2 |
In this work we design graph neural network architectures that capture
optimal approximation algorithms for a large class of combinatorial
optimization problems, using powerful algorithmic tools from semidefinite
programming (SDP). Concretely, we prove that polynomial-sized message-passing
algorithms can represent the ... | http://arxiv.org/abs/2310.00526v7 |
Molecular polaritons arise when molecules interact so strongly with light
that they become entangled with each other. This light-matter hybridization
alters the chemical and physical properties of the molecular system and allows
chemical reactions to be controlled without the use of external fields. We
investigate the ... | http://arxiv.org/abs/2307.14822v1 |
The landscape of image generation has been forever changed by open vocabulary
diffusion models. However, at their core these models use transformers, which
makes generation slow. Better implementations to increase the throughput of
these transformers have emerged, but they still evaluate the entire model. In
this paper... | http://arxiv.org/abs/2303.17604v1 |
We provide a practical technique to obtain plenty of algebraic relations for
theta functions on the bounded symmetric domains of type $I$. In our framework,
each theta relation is controlled by combinatorial properties of a pair $(T,P)$
of a regular matrix $T$ over an imaginary quadratic field and a
positive-definite H... | http://arxiv.org/abs/2301.09243v2 |
Fully realizing the potential of multigrid solvers often requires custom
algorithms for a given application model, discretizations and even regimes of
interest, despite considerable effort from the applied math community to
develop fully algebraic multigrid (AMG) methods for almost 40 years. Classic
geometric multigrid... | http://arxiv.org/abs/2302.10242v1 |
The n_TOF facility has just undergone in 2021 a major upgrade with the
installation of its third generation spallation target that has been designed
to optimize the performance of the two n_TOF time-of-flight lines. This
contribution describes the key features and limitations for capture
measurements in the two beam li... | http://arxiv.org/abs/2303.08724v1 |
Multipliers are widely-used arithmetic operators in digital signal processing
and machine learning circuits. Due to their relatively high complexity, they
can have high latency and be a significant source of power consumption. One
strategy to alleviate these limitations is to use approximate computing. This
paper thus ... | http://arxiv.org/abs/2310.10053v1 |
ASASSN-15cm had been identified as a dwarf nova with an orbital period of 5.0
hours and a hot, luminous secondary of of a spectral type around K2.5 in the
previous study. Using the Zwicky Transient Facility (ZTF) data, the Asteroid
Terrestrial-impact Last Alert System (ATLAS) forced photometry and the All-Sky
Automated... | http://arxiv.org/abs/2302.09713v1 |
