Analytical relations for the bound state spectrum of gauge theories with a Brout-Englert-Higgs mechanism
René Sondenheimer
We apply the method proposed by Fröhlich, Morchio, and Strocchi to analyze the bound state spectrum of various gauge theories with a Brout-Englert-Higgs mechanism. These serve as b…
Electronic structure and superconductivity of the non-centrosymmetric SnAs
C. A. Marques, M. J. Neat, C. M. Yim +9
In a superconductor that lacks inversion symmetry, the spatial part of the Cooper pair wave function has a reduced symmetry, allowing for the mixing of spin-singlet and spin-triple…
A Hot Cusp-Shaped Confined Solar Flare
Aaron Hernandez-Perez, Yang Su, Julia K. Thalmann +5
We analyze a confined flare that developed a hot cusp-like structure high in the corona (H ~ 66 Mm). A growing cusp-shaped flare arcade is a typical feature in the standard model o…
Clean group rings over localizations of rings of integers
Yuanlin Li, Qinghai Zhong
A ring is said to be clean if each element of can be written as the sum of a unit and an idempotent. In a recent article (J. Algebra, 405 (2014), 168-178), Immormino and Mc…
On half-factoriality of transfer Krull monoids
Weidong Gao, Chao Liu, Salvatore Tringali +1
Let be a transfer Krull monoid over a subset of an abelian group with finite exponent. Then every non-unit can be written as a finite product of atoms, say $…
Versatile stabilized finite element formulations for nearly and fully incompressible solid mechanics
Elias Karabelas, Gundolf Haase, Gernot Plank +1
Computational formulations for large strain, polyconvex, nearly incompressible elasticity have been extensively studied, but research on enhancing solution schemes that offer bette…
On product-one sequences over dihedral groups
Alfred Geroldinger, David J. Grynkiewicz, Jun Seok Oh +1
Let be a finite group. A sequence over means a finite sequence of terms from , where repetition is allowed and the order is disregarded. A product-one sequence is a sequ…
Exploring the Tan contact term in Yang-Mills theory
Ouraman Hajizadeh, Markus Q. Huber, Axel Maas +1
Reliably computing the free energy in a gauge theory like QCD is a challenging and resource-demanding endeavor. As an alternative, we explore here the possibility to obtain the ass…
Dense two-color QCD from Dyson-Schwinger equations
Romain Contant, Markus Q. Huber
We investigate quantum chromodynamics with two colors at nonvanishing density using Dyson-Schwinger equations. Lattice methods do not have a complex action problem in this theory.…
Spectral dimension as a tool for analyzing non-perturbative propagators
Wolfgang Kern, Markus Q. Huber, Reinhard Alkofer
We derive general properties of the scale-dependent effective spectral dimensions of non-perturbative gauge boson propagators as they appear as solutions from different methods in…
Thermopower of the electron-doped manganese pnictide LaMnAsO
Manuel Zingl, Gernot J. Kraberger, Markus Aichhorn
Upon chemical substitution of oxygen with fluor, LaMnAsO has been electron-doped in experiments, resulting in samples with remarkably high Seebeck coefficients of around -300$μVK^{…
Understanding Phonon Properties in Isoreticular Metal-Organic Frameworks from First Principles
Tomas Kamencek, Natalia Bedoya-Martínez, Egbert Zojer
Metal-organic frameworks (MOFs) are crystalline materials consisting of metal centers and organic linkers forming open and porous structures. They have been extensively studied due…
prediction of a two-dimensional variant of the iridate IrO
Andriy Smolyanyuk, Markus Aichhorn, I. I. Mazin +1
We propose an insulating 2D phase of IrO, predicted by evolutionary algorithms. The predicted phase is a van der Waals crystal, in which Ir forms a trian…
On the effect of resonances in the quark-photon vertex
Ángel S. Miramontes, Hèlios Sanchis-Alepuz
A calculation of hadronic timelike form factors in the Poincaré-covariant Bethe-Salpeter formalism necessitates knowing the analytic structure of the non-perturbative quark-photon…
Bayesian parametric analytic continuation of Green's functions
Michael Rumetshofer, Daniel Bauernfeind, Wolfgang von der Linden
Bayesian parametric analytic continuation (BPAC) is proposed for the analytic continuation of noisy imaginary-time Green's function data as, e.g., obtained by continuous-time quant…
Mutation of type friezes
A. Garcia Elsener, K. Serhiyenko
In this article we study mutation of friezes of type . We provide a combinatorial formula for the entries in a frieze after mutation. The two main ingredients in the proof inclu…
Pre-eruption processes: heating, particle acceleration and the formation of a hot channel before the 2012 October 20 M9.0 limb flare
Aaron Hernandez-Perez, Yang Su, Astrid M. Veronig +3
We report a detailed study of the pre-eruption activities that led to the occurrence of an M9.0 flare/CME event on 2012 October 20 in NOAA AR 11598. This includes the study of the…
The quenched SU(2) scalar-gluon vertex in minimal Landau gauge
Axel Maas
The question of whether confining effects are visible in correlation functions is a long-standing one. Complementing investigations on the propagators of fundamental and adjoint sc…
Scheme dependence of asymptotically free solutions
Holger Gies, René Sondenheimer, Alessandro Ugolotti +1
Recent studies have provided evidence for the existence of new asymptotically free trajectories in non-Abelian particle models without asymptotic symmetry in the high-energy limit.…
