Bound-State Spectra of a Lifshitz-Type Dirac Equation in (2+1) Dimensions
Lucas K. R. Queiroz, Van Sérgio Alves, Nilberto Bezerra +2
We investigate a Dirac-type equation in dimensions modified by Lifshitz spatial derivatives with dynamical exponent , focusing on the spectral properties of bound-stat…
Transport of Dirac magnons driven by gauge fields
Luis Fernández, Ka Shen, Leandro O. Nascimento +3
We present a unified quantum field theory for Dirac magnons coupled to emergent gauge fields. At zero temperature, any space- and time-dependent gauge perturbation drives magnons o…
Podolsky quantum electrodynamics for strongly coupled Dirac fermions in (2+1)D
Carlos A. P. C. Junior, Leandro O. Nascimento, Van Sérgio Alves
We investigate generalized quantum electrodynamics (GQED), a higher-derivative extension of quantum electrodynamics in (3+1) dimensions. We perform a dimensional reduction of this…
Dynamical mass generation and critical behavior in pseudo-Proca quantum electrodynamics
Helio G. Barroso, Van Sérgio Alves, Leandro O. Nascimento
We investigate dynamical mass generation in pseudo-Proca quantum electrodynamics (PPQED) by means of Schwinger--Dyson equations in rainbow-quenched and unquenched truncations. The…
Renormalization of the optical band gap through an effective Thirring interaction for massive Dirac-like electrons
Nilberto Bezerra, Van Sérgio Alves, Leandro O. Nascimento +1
We analyze mass renormalization in massive Dirac-like systems in (2+1) dimensions arising from electron-phonon interactions at finite temperatures, employing the large- expansio…
Renormalization of the band gap in 2D materials near an interface between two dielectrics
Alessandra N. Braga, Wagner P. Pires, Jeferson Danilo L. Silva +2
We investigate how the renormalization of the band gap in a planar 2D material is affected by the consideration of two nondispersive semi-infinite dielectrics, with dielectric cons…
Effects of the two-dimensional Coulomb interaction in both Fermi velocity and energy gap for Dirac-like electrons at finite temperature
Nilberto Bezerra, Van Sérgio Alves, Leandro O. Nascimento +1
We describe both the Fermi velocity and the mass renormalization due to the two-dimensional Coulomb interaction in the presence of a thermal bath. To achieve this, we consider an a…
