Spectral properties of the 2D magnetic Weyl-Dirac operator with a short-range potential
M. B. Alves, O. M. Del Cima, D. H. T. Franco +1
This paper is devoted to the study of the spectral properties of the Weyl-Dirac or massless Dirac operators, describing the behavior of quantum quasi-particles in dimension 2 in a…
Non-trivial effect of dephasing: Enhancement of rectification of spin current in graded XX chains
Saulo H. S. Silva, Gabriel T. Landi, Emmanuel Pereira
In order to reveal mechanisms to control and manipulate spin currents, we perform a detailed investigation of the dephasing effects in the open XX model with a Lindblad dynamics in…
Heat rectification on the XX chain
Saulo H. S. Silva, Gabriel T. Landi, Raphael C. Drumond +1
In order to better understand the minimal ingredients for thermal rectification, we perform a detailed investigation of a simple spin chain, namely, the open XX model with a Lindbl…
Rectification induced by geometry in two-dimensional quantum spin lattices
Alessandra Chioquetta, Emmanuel Pereira, Gabriel T. Landi +1
We address the role of geometrical asymmetry in the occurrence of spin rectification in two-dimensional quantum spin chains subject to two reservoirs at the boundaries, modeled by…
Transport in boundary-driven quantum spin systems: One-way street for the energy current
Deborah Oliveira, Emmanuel Pereira, Humberto C. F. Lemos
We study transport properties in boundary-driven asymmetric quantum spin chains given by and Heisenberg models. Our approach exploits symmetry transfo…
Beyond the Lindblad Master Equation: Heat, Work and Energy Currents in Boundary Driven Spin Chains
Luís H. Reis, Saulo H. S. Silva, Emmanuel Pereira
We consider the accurate investigation of the energy current and its components, heat and work, in some boundary driven quantum spin systems. The expressions for the currents, as w…
