Disorder-safe entanglement transfer through ladder qubit chains
Guilherme M. A. Almeida, Andre M. C. Souza, Francisco +3
We study an entanglement transfer protocol in a two-leg ladder spin-1/2 chain in the presence of disorder. In the regime where on-site energies and the intrachain couplings follow…
Coexistence of extended and localized states in one-dimensional systems
Andre M. C. Souza, Roberto. F. S. Andrade
Mobility edge transitions from localized to extended states have been observed in two and three dimensional systems, for which sound theoretical explanations have also been derived…
Noncommutative quantum Hall effect in graphene
Willien O. Santos, Guilherme M. A. Almeida, Andre M. C. Souza
We discuss the quantum Hall effect on a single-layer graphene in the framework of noncommutative (NC) phase space. We find it induces a shift in the Hall resistivity. Furthermore,…
Metastable transitions in inertial Langevin systems: what can be different from the overdamped case?
Andre Souza, Molei Tao
Metastable transitions in Langevin dynamics can exhibit rich behaviors that are markedly different from its overdamped limit. In addition to local alterations of the transition pat…
Thermodynamic Framework for Compact q-Gaussian Distributions
Andre M. C. Souza, Roberto F. S. Andrade, Fernando D. Nobre +1
Recent works have associated systems of particles, characterized by short-range repulsive interactions and evolving under overdamped motion, to a nonlinear Fokker-Planck equation w…
Entanglement can preserve the compact nature of the phase-space occupancy
Andre M. C. Souza, Peter Rapčan, Constantino Tsallis
We study the one-dimensional transverse-field spin-1/2 Ising ferromagnet at its critical point. We consider an -sized subsystem of a -sized ring, and trace over the states of…
