Influence of the four-fermion interactions in (2+1)D massive electrons system
Luis Fernández, Van Sérgio Alves, M. Gomes +2
The description of the electromagnetic interaction in two-dimensional Dirac materials, such as graphene and transition-metal dichalcogenides, in which electrons move in the plane a…
Dynamical Mass Generation in Pseudo Quantum Electrodynamics with Gross-Neveu Interaction at finite temperature
Luis Fernández, Reginaldo O. Corrêa, Van Sérgio Alves +2
We study the dynamical mass generation in Pseudo Quantum Electrodynamics (PQED) coupled to the Gross-Neveu (GN) interaction, in (2+1) dimensions, at both zero and finite temperatur…
Renormalization of the band gap in 2D materials through the competition between electromagnetic and four-fermion interactions
Luis Fernández, Van Sérgio Alves, Leandro O. Nascimento +3
Recently the renormalization of the band gap , in both WSe and MoS, has been experimentally measured as a function of the carrier concentration . The main result esta…
Superconducting and Pseudogap Transition Temperatures in High-Tc Cuprates and the Dependence on Pressure
E. C. Marino, Reginaldo O. Corrêa, R. Arouca +2
We derive analytic expressions for the critical temperatures of the superconducting (SC) and pseudogap (PG) transitions of the high-Tc cuprates as a function of doping. These are i…
Projected Proca Field Theory: a One-Loop Study
R. F. Ozela, Van Sérgio Alves, E. C. Marino +4
The recent discovery of two-dimensional Dirac materials, such as graphene and transition-metaldichalcogenides, has raised questions about the treatment of hybrid systems, in which…
Bosonic interactions in a nonlocal theory in (2+1) dimensions
Ygor Pará, Van Sérgio Alves, Tommaso Macrì +2
Pseudo-Quantum Electrodynamics (PQED) provides an excellent description of the interaction between charged particles confined to a plane. When we couple pseudo-gauge field with a b…
