Phase diagram of QCD in a magnetic field: A review
Jens O. Andersen, William R. Naylor, Anders Tranberg
We review in detail recent advances in our understanding of the phase structure and the phase transitions of hadronic matter in strong magnetic fields and zero quark chemical p…
Eddy current interactions in a Ferromagnet-Normal metal bilayer structure, and its impact on ferromagnetic resonance lineshapes
Vegard Flovik, Ferran Macià, Andrew D. Kent +1
We investigate the effect of eddy currents on ferromagnetic resonance (FMR) in ferromagnet-normal metal (FM/NM) bilayer structures. Eddy-current effects are usually neglected for N…
On The Modeling of OpenFlow-based SDNs: The Single Node Case
Kashif Mahmood, Ameen Chilwan, Olav N. Østerbø +1
OpenFlow is one of the most commonly used protocols for communication between the controller and the forwarding element in a software defined network (SDN). A model based on M/M/1…
Finite-rank Bratteli-Vershik diagrams are expansive -- a new proof
Siri-Malén Høynes
In the paper "Finite-rank Bratteli-Vershik diagrams are expansive" [DM], Downarowicz and Maass proved that the Cantor minimal system associated to a properly ordered Bratteli diagr…
Magnonic Charge Pumping via Spin-Orbit Coupling
Chiara Ciccarelli, Kjetil M. D. Hals, Andrew Irvine +5
The interplay between spin, charge, and orbital degrees of freedom has led to the development of spintronic devices like spin-torque oscillators, spin-logic devices, and spin-trans…
Equation of State for QCD at finite temperature and density. Resummation versus lattice data
Jens O. Andersen, Najmul Haque, Munshi G. Mustafa +2
The perturbative series for finite-temperature field theories has very poor convergence properties and one needs a way to reorganize it. In this talk, I review two ways of reorgani…
Non-Perturbative Theory for Dispersion Self-Energy of Atoms
Priyadarshini Thiyam, C. Persson, I. Brevik +2
We go beyond the approximate series-expansions used in the dispersion theory of finite size atoms. We demonstrate that a correct, and non-perturbative, theory dramatically alters t…
Morphisms between indecomposable complexes in the bounded derived category of a gentle algebra
Kristin Krogh Arnesen, Rosanna Laking, David Pauksztello
In this article we provide a simple combinatorial description of morphisms between indecomposable complexes in the bounded derived category of a gentle algebra.
The multiplicative Hilbert matrix
Ole Fredrik Brevig, Karl-Mikael Perfekt, Kristian Seip +2
It is observed that the infinite matrix with entries for appears as the matrix of the integral operator $\mathbf{H}f(s):=\int_{1/2}^{+\infty…
Helson's problem for sums of a random multiplicative function
Andriy Bondarenko, Kristian Seip
We consider the random functions , where is the completely multiplicative random function generated by independent Steinhaus variables . It…
The homology of the Higman-Thompson groups
Markus Szymik, Nathalie Wahl
We prove that Thompson's group is acyclic, answering a 1992 question of Brown in the positive. More generally, we identify the homology of the Higman-Thompson groups …
Decorated marked surfaces II: Intersection numbers and dimensions of Homs
Yu Qiu, Yu Zhou
We study the 3-Calabi-Yau categories arising from quivers with potential associated to a decorated marked surface introduced by the first…
Homological epimorphisms, recollements and Hochschild cohomology - with a conjecture by Snashall-Solberg in view
Reiner Hermann
We show that recollements of module categories give rise to homomorphisms between the associated Hochschild cohomology algebras which preserve the strict Gerstenhaber structure, i.…
Inverse magnetic catalysis and regularization in the quark-meson model
Jens O. Andersen, William R. Naylor, Anders Tranberg
Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate…
Frobenius and the derived centers of algebraic theories
William G. Dwyer, Markus Szymik
We show that the derived center of the category of simplicial algebras over every algebraic theory is homotopically discrete, with the abelian monoid of components isomorphic to th…
Anderson Localization and Quantum Hall Effect: Numerical Observation of Two Parameter Scaling
Miklós Antal Werner, Arne Brataas, Felix von Oppen +1
A two dimensional disordered system of non-interacting fermions in a homogeneous magnetic field is investigated numerically. By introducing a new magnetic gauge, we explore the ren…
Dark Energy Coupled with Dark Matter in Viscous Fluid Cosmology
I. Brevik, V. V. Obukhov, A. V. Timoshkin
We investigate cosmological models with two interacting fluids: dark energy and dark matter in flat Friedmann-Robertson-Walker universe. The interaction between dark energy and dar…
Graph algebras and orbit equivalence
Nathan Brownlowe, Toke Meier Carlsen, Michael F. Whittaker
We introduce the notion of orbit equivalence of directed graphs, following Matsumoto's notion of continuous orbit equivalence for topological Markov shifts. We show that two graphs…
Brane Viscous Cosmology in the Plasma Era
Iver Brevik
We consider how the five-dimensional Randall-Sundrum (one-brane) theory becomes modified when account is taken of the bulk viscosity of the cosmic fluid on the brane. We focus on t…
Josephson-frustrated superconductors in a magnetic field
Troels Arnfred Bojesen, Asle Sudbø
We study the effect of an externally imposed rotation or magnetic field on frustrated multiband superconductors/superfluids. The frustration originates with multiple superconductin…
On the integration of stochastic rigid body with geometric numerical schemes
Nataliya Ramzina
In the present paper we investigate the performance of explicit splitting schemes and related techniques applied to a rigid body model subject to a stochastic torque and random per…
Stochastic Discriminative EM
Andres R. Masegosa
Stochastic discriminative EM (sdEM) is an online-EM-type algorithm for discriminative training of probabilistic generative models belonging to the exponential family. In this work,…
The Lie group of real analytic diffeomorphisms is not real analytic
Rafael Dahmen, Alexander Schmeding
We construct an infinite dimensional real analytic manifold structure for the space of real analytic mappings from a compact manifold to a locally convex manifold. Here a map is re…
On Optimum Asymptotic Multiuser Efficiency of Randomly Spread CDMA
Mohammad Ali Sedaghat, Ralf Müller, Farokh Marvasti
We extend the result by Tse and Verdú on the optimum asymptotic multiuser efficiency of randomly spread CDMA with Binary Phase Shift Keying (BPSK) input. Random Gaussian and random…
