Quantum Field Theory Approach to the Optical Conductivity of Strained and Deformed Graphene
W. de Paula, a. Chaves, O. Oliveira +1
The computation of the optical conductivity of strained and deformed graphene is discussed within the framework of quantum field theory in curved spaces. The analytical solutions o…
Anderson localization of light in disordered superlattices containing graphene layers
A. J. Chaves, N. M. R. Peres, F. A. Pinheiro
We theoretically investigate light propagation and Anderson localization in one-dimensional disordered superlattices composed of dielectric stacks with graphene sheets in between.…
Bound vortex states and exotic lattices in multi-component Bose-Einstein condensates: The role of vortex-vortex interaction
Davi S. Dantas, Aristeu R. P. Lima, A. Chaves +3
We numerically study the vortex-vortex interaction in multi-component homogeneous Bose-Einstein condensates within the realm of the Gross-Pitaevskii theory. We provide strong evide…
Anisotropic exciton Stark shift in black phosphorus
Andrey Chaves, T. Low, P. Avouris +2
We calculate the excitonic spectrum of few-layer black phosphorus by direct diagonalization of the effective mass Hamiltonian in the presence of an applied in-plane electric field.…
