Two-dimensional Yukawa interaction driven by a nonlocal-Proca quantum electrodynamics
Van Sérgio Alves, Tommaso Macrì, Gabriel C. Magalhães +2
We derive two versions of an effective model to describe dynamical effects of the Yukawa interaction among Dirac electrons in the plane. Such short-range interaction is obtained by…
Quantum-electrodynamical approach to the exciton spectrum in Transition-Metal Dichalcogenides
E. C. Marino, Leandro O. Nascimento, Van Sérgio Alves +2
Manipulation of intrinsic electron degrees of freedom, such as charge and spin, gives rise to electronics and spintronics, respectively. Electrons in monolayer materials with a hon…
Dynamical Mass Generation in Pseudo Quantum Electrodynamics with Four-Fermion Interactions
Van Sérgio Alves, Reginaldo O. C. Junior, E. C. Marino +1
We describe dynamical symmetry breaking in a system of massless Dirac fermions with both electromagnetic and four-fermion interactions in (2+1) dimensions. The former is described…
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…
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…
