Chiral symmetry breaking in models with unconventional supersymmetry
Pedro D. Alvarez, Cristian Villavicencio, Jorge Zanelli
We investigate dynamical mass generation in a geometrically constructed gauge theory based on the super Lie algebra , in which gravity, Yang-Mills fields, and fermions a…
Heat Capacity Anomalies and Thermal Crossovers in Finite Su-Schrieffer-Heeger Chains
Carlos Magno da Conceição, Julio César Pérez-Pedraza, Alfredo Raya +1
We investigate the thermodynamic properties of finite Su-Schrieffer-Heeger (SSH) chains in thermal equilibrium at fixed temperature and chemical potential. Using the canonical and…
Strongly interacting matter in extreme magnetic fields
Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58
Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
Quark anomalous magnetic moment in an extreme magnetic background from perturbative QCD
Eduardo S. Fraga, Leticia F. Palhares, Cristian Villavicencio
We compute the one-loop QCD correction to the photon-quark-antiquark vertex in an extremely strong magnetic background, i.e., one in which is much larger than all other…
Finite-energy sum rules at finite chemical potential and zero temperature
Alfredo Raya, Cristian Villavicencio
In this article we explore the effect of chemical potential at zero temperature in the implementation of in-medium effects in the perturbative sector in finite energy sum rules. Fo…
The pseudo chiral magnetic effect in QED3
A. J. Mizher, A. Raya, C. Villavicencio
Chiral magnetic effect (CME) has been suggested to take place during peripheral relativistic heavy ion collisions. However, signals of its realization are not yet independent of am…
Quark mass and isospin dependence of the deconfining critical temperature
E. S. Fraga, L. F. Palhares, C. Villavicencio
We describe the deconfining critical temperature dependence on the pion mass and on the isospin chemical potential in remarkably good agreement with lattice data. Our framework inc…
Weinberg power counting and the quark determinant at small chemical potential
E. S. Fraga, C. Villavicencio
We construct an effective action for QCD by expanding the quark determinant in powers of the chemical potential at finite temperature in the case of massless quarks. To cut the inf…
