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).…
The influence of a conducting surface on the conductivity of graphene
D. C. Pedrelli, D. T. Alves, V. S. Alves
In the present paper, using Pseudo-Quantum Electrodynamics to describe the interaction between electrons in graphene, we investigate the longitudinal and optical conductivities of…
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…
The influence of a weak magnetic field in the Renormalization-Group functions of (2+1)-dimensional Dirac systems
N. Menezes, Van Sergio Alves, C. Morais Smith
The experimental observation of the renormalization of the Fermi velocity as a function of doping has been a landmark for confirming the importance of electronic interactio…
Spin g-factor due to electronic interactions in graphene
N. Menezes, Van Sergio Alves, E. C. Marino +3
The gyromagnetic factor is an important physical quantity relating the magnetic-dipole moment of a particle to its spin. The electron spin g-factor in vacuo is one of the best mode…
Suppressing vacuum fluctuations with vortex excitations
J. F. de Medeiros Neto, Rudnei O. Ramos, Carlos Rafael M. Santos +3
The Casimir force for a planar gauge model is studied considering perfect conducting and perfect magnetically permeable boundaries. By using an effective model describing planar vo…
Chiral-Symmetry Breaking in Pseudo Quantum Electrodynamics at Finite Temperature
Leandro O. Nascimento, Van Sérgio Alves, Francisco Peña +2
We use the Schwinger-Dyson equations in the presence of a thermal bath, in order to study chiral symmetry breaking in a system of massless Dirac fermions interacting through pseudo…
Interaction Induced Quantum Valley Hall Effect in Graphene
E. C. Marino, Leandro O. Nascimento, Van Sergio Alves +1
We use Pseudo Quantum Electrodynamics (PQED) in order to describe the full electromagnetic interaction of the p-electrons of graphene in a consistent 2D formulation. We first consi…
