Density screening effects in the NJL model: Chiral condensate, speed of sound, and the Critical End Point
Alejandro Rosas Díaz, Alfredo Raya, C. A. Vaquera Araujo +1
The phase diagram of Quantum Chromodynamics (QCD) remains a central topic in high-energy physics. At high temperature and low baryochemical potential, the chiral transition is expe…
Impact of impurities on the topological boundaries and edge state localization in a staggered chain of atoms: SSH model and its topoelectrical circuit realization
Julio César Pérez-Pedraza, José Eduardo Barrios-Vargas, Alfredo Raya
We study the Su-Schrieffer-Hegger model, perhaps the simplest realization of a topological insulator, in the presence of an embedded impurity superlattice. We consider the impact o…
Robust features of QCD phase diagram through a Contact Interaction model for quarks: A view from the effective potential
Aftab Ahmad, Muhammad Azher, Alfredo Raya
Our research delves into the QCD phase diagram in the temperature and quark chemical potential plane. We use a unique confining contact interaction effective model of quark…
Dirac materials in parallel non-uniform electromagnetic fields generated by SUSY: A new class of chiral Planar Hall Effect?
Julio Cesar Pérez-Pedraza, Juan D. García-Muñoz, A. Raya
Within a Supersymmetric Quantum Mechanics (SUSY-QM) framework, the (3+1) Dirac equation describing a Dirac material in the presence of external parallel electric and magnetic field…
Extended transfer matrix method for electron transmission in anisotropic 2D materials: Interplay of strain and (a)periodicity of potentials
Erik Díaz-Bautista, Yonatan Betancur-Ocampo, Alfredo Raya
We extend the conventional transfer matrix method to include anisotropic features for electron transmission in two-dimensional materials, such as breaking reflection law in pseudo-…
Electron-Photon Vertex and Dynamical Chiral Symmetry Breaking in Reduced QED: An Advanced Study of Gauge Invariance
L. Albino, A. Bashir, A. J. Mizher +1
We study the effect of a refined electron-photon vertex on the dynamical breaking of chiral symmetry in reduced quantum electrodynamics. We construct an educated {\em ansatz} for t…
