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…

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…
