Entanglement modes and topological phase transitions in superconductors
T. P. Oliveira, P. D. Sacramento
Topological insulators and topological superconductors display various topological phases that are characterized by different Chern numbers or by gapless edge states. In this work…

Entanglement entropy and entanglement spectrum of triplet topological superconductors
T. P. Oliveira, P. Ribeiro, P. D. Sacramento
We analyse the entanglement entropy properties of a two-dimensional p-wave superconductor with Rashba spin-orbit coupling, which displays a rich phase-space that supports non-trivi…

Mean-field calculation of critical parameters and log-periodic characterization of an aperiodic-modulated model
T. P. Oliveira, N. S. Branco
We employ a mean-field approximation to study the Ising model with aperiodic modulation of its interactions in one spatial direction. Two different values for the exchange constant…
