Bosonization, mass generation, and the pseudo Chern-Simons action
Gabriel C. Magalhães, Van S. Alves, Leandro O. Nascimento +1
We discuss several aspects of a generalization of the Chern-Simons action containing the pseudo-differential operator, which we shall call pseudo Chern-Simons (PCS).…
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…
Pseudo Quantum Electrodynamics and Chern-Simons theory Coupled to Two-dimensional Electrons
Gabriel C. Magalhães, Van S. Alves, Eduardo C. Marino +1
We study a nonlocal theory that combines both the Pseudo quantum electrodynamics (PQED) and Chern-Simons actions among two-dimensional electrons. In the static limit, we conclude t…
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…
Bounded particle interactions driven by a nonlocal dual Chern-Simons model
Van Sérgio Alves, E. C. Marino, Leandro O. Nascimento +3
Quantum electrodynamics (QED) of electrons confined in a plane and that yet can undergo interactions mediated by an unconstrained photon has been described by the so-called {\it ps…
