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…
Chern-Simons theory and atypical Hall conductivity in the Varma phase
N. Menezes, C. Morais Smith, Giandomenico Palumbo
In this letter, we analyze the topological response of a fermionic model defined on the Lieb lattice in presence of an electromagnetic field. The tight-binding model is built in te…
Excitonic gap generation in thin-film topological insulators
N. Menezes, C. Morais Smith, Giandomenico Palumbo
In this work, we analyze the excitonic gap generation in the strong-coupling regime of thin films of three-dimensional time-reversal-invariant topological insulators. We start by w…
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…
Conformal QED in two-dimensional topological insulators
N. Menezes, Giandomenico Palumbo, C. Morais Smith
It has been shown recently that local four-fermion interactions on the edges of two-dimensional time-reversal-invariant topological insulators give rise to a new non-Fermi-liquid p…
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…
