Geometric Inflation
Gustavo Arciniega, Pablo Bueno, Pablo A. Cano +3
We argue that the presence of an inflationary epoch is a natural, almost unavoidable, consequence of the existence of a sensible effective action involving an infinite tower of hig…
Noise-Assisted Quantum Exciton and Electron Transfer in Bio-Complexes with Finite Donor and Acceptor Bandwidths
Alexander I. Nesterov, Gennady P. Berman, Marco Merkli +1
We present an analytic and numerical study of noise-assisted quantum exciton (electron) transfer (ET) in a bio-complex, consisting of an electron donor and acceptor (a dimer), mode…
Extended crossover from Fermi liquid to quasi-antiferromagnet in the half-filled 2D Hubbard model
Fedor Šimkovic, J. P. F. LeBlanc, Aaram J. Kim +4
The ground state of the Hubbard model with nearest-neighbor hopping on the square lattice at half filling is known to be that of an antiferromagnetic (AFM) band insulator for any o…
Existence and Uniqueness of Near-Horizon Geometries for 5-Dimensional Black Holes
Aghil Alaee, Marcus Khuri, Hari Kunduri
We prove existence of all possible bi-axisymmetric near-horizon geometries of 5-dimensional minimal supergravity. These solutions possess the cross-sectional horizon topology …
Updated Core Libraries of the ALPS Project
Markus Wallerberger, Sergei Iskakov, Alexander Gaenko +13
The open source ALPS (Algorithms and Libraries for Physics Simulations) project provides a collection of physics libraries and applications, with a focus on simulations of lattice…
Prescribing capacitary curvature measures on planar convex domains
J. Xiao
For and a bounded, convex, nonempty, open set let be the -capacitary curvature measure (generated by the closure of…
The moduli space of real vector bundles of rank two over a real hyperelliptic curve
Thomas John Baird, Shengda Hu
The Desale-Ramanan Theorem is an isomorphism between the moduli space of rank two vector bundles over complex hyperelliptic curve and the variety of linear subspaces in an intersec…
Group gradings on the Lie and Jordan algebras of block-triangular matrices
Mikhail Kochetov, Felipe Yasumura
We classify up to isomorphism all gradings by an arbitrary group on the Lie algebras of zero-trace upper block-triangular matrices over an algebraically closed field of charact…
Graded polynomial identities as identities of universal algebras
Yuri Bahturin, Felipe Yasumura
Let and be finite-dimensional simple algebras with arbitrary signature over an algebraically closed field. Suppose and are graded by a semigroup so that the gra…
Multi-scale Convolution Aggregation and Stochastic Feature Reuse for DenseNets
Mingjie Wang, Jun Zhou, Wendong Mao +1
Recently, Convolution Neural Networks (CNNs) obtained huge success in numerous vision tasks. In particular, DenseNets have demonstrated that feature reuse via dense skip connection…
Semi-dense Stereo Matching using Dual CNNs
Wendong Mao, Mingjie Wang, Jun Zhou +1
A robust solution for semi-dense stereo matching is presented. It utilizes two CNN models for computing stereo matching cost and performing confidence-based filtering, respectively…
New thermodynamic identities for five-dimensional black holes
Hari K. Kunduri, James Lucietti
We derive new identities for the thermodynamic variables of five-dimensional, asymptotically flat, stationary and biaxisymmetric vacuum black holes. These identities depend on the…
Generalized symmetries and conservation laws of (1+1)-dimensional Klein-Gordon equation
Stanislav Opanasenko, Roman O. Popovych
Using advantages of nonstandard computational techniques based on the light-cone variables, we explicitly find the algebra of generalized symmetries of the (1+1)-dimensional Klein-…
A Perfect One-Factorisation of
David A. Pike
In 1963, Anton Kotzig conjectured that for each the complete graph has a perfect one-factorisation (i.e., a decomposition into perfect matchings such that each…
Evading the Trans-Planckian problem with Vaidya spacetimes
Ivan Booth, Bradley Creelman, Jessica Santiago +1
Hawking radiation, when treated in the ray optics limit, exhibits the unfortunate trans-Planckian problem --- a Hawking photon near spatial infinity, if back-tracked to the immedia…
General volumes in the Orlicz-Brunn-Minkowski theory and a related Minkowski Problem II
Richard J. Gardner, Daniel Hug, Sudan Xing +1
The general dual volume $\dveV(K)$ and the general dual Orlicz curvature measure $\deV(K, \cdot)$ were recently introduced for functions $G: (0, \infty)\times \sphere\rightarrow (0…
Entangling detectors in anti-de Sitter space
Laura J. Henderson, Robie A. Hennigar, Robert B. Mann +2
We examine in -dimensional anti-de Sitter (AdS) space the phenomena of entanglement harvesting - the process in which a pair of detectors (two-level atoms) extract entanglem…
Mixed-ADC/DAC Multipair Massive MIMO Relaying Systems: Performance Analysis and Power Optimization
Jiayi Zhang, Linglong Dai, Ziyan He +2
High power consumption and expensive hardware are two bottlenecks for practical massive multiple-input multiple-output (mMIMO) systems. One promising solution is to employ low-reso…
DensSiam: End-to-End Densely-Siamese Network with Self-Attention Model for Object Tracking
Mohamed H. Abdelpakey, Mohamed S. Shehata, Mostafa M. Mohamed
Convolutional Siamese neural networks have been recently used to track objects using deep features. Siamese architecture can achieve real time speed, however it is still difficult…
Phase transitions in fluctuations and their role in two-step nucleation
Daniella James, Seamus Beairsto, Carmen Hartt +4
We consider the thermodynamic behavior of local fluctuations occurring in a stable or metastable bulk phase. For a system with three or more phases, a simple analysis based on clas…
Algorithmic Matsubara Integration for Hubbard-like models
Amir Taheridehkordi, S. H. Curnoe, J. P. F. LeBlanc
We present an algorithm to evaluate Matsubara sums for Feynman diagrams comprised of bare Green's functions with single-band dispersions with local U Hubbard interaction vertices.…
Variational integrator for the rotating shallow-water equations on the sphere
Rüdiger Brecht, Werner Bauer, Alexander Bihlo +2
We develop a variational integrator for the shallow-water equations on a rotating sphere. The variational integrator is built around a discretization of the continuous Euler-Poinca…
