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…
Screening and Topological Order in Thin Superconducting Films
E. C. Marino, D. Niemeyer, Van Sérgio Alves +2
We derive an effective two-dimensional low-energy theory for thin superconducting films coupled to a three-dimensional fluctuating electromagnetic field. Using this theory we discu…
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…
Quantum Valley Hall Effect in Massive Dirac Systems Coupled to a Scalar Field
S. H. Kooi, N. Menezes, Van Sérgio Alves +1
We use Pseudo Quantum Electrodynamics to study massive (2+1)D Dirac systems interacting electromagnetically via a U(1) gauge field in (3+1)D. It was recently found in Ref. [1], tha…
Emerging Quantum Hall Effect in Massive Dirac Systems
Leandro O. Nascimento, E. C. Marino, Van Sérgio Alves +1
An interaction-driven nonzero quantum Hall conductivity is shown to occur in time-reversal symmetric massive Dirac materials, in the absence of any external agent. The effect is pr…
