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…
Microscopic theory of a non-equilibrium open bosonic chain
Jader P. Santos, Gabriel T. Landi
Quantum master equations form an important tool in the description of transport problems in open quantum systems. However, they suffer from the difficulty that the shape of the Lin…
Non-equilibrium quantum chains under multi-site Lindblad baths
Pedro H. Guimarães, Gabriel T. Landi, Mario J. de Oliveira
We study a quantum XX chain coupled to two heat reservoirs that act on multiple-sites and are kept at different temperatures and chemical potentials. The baths are described by Lin…
Energy Rectification in Quantum Graded Spin Chains: Analysis of the XXZ Model
Luvas Schuab, Emmanuel Pereira, Gabriel T. Landi
In this work, with focus on the energy transport properties in quantum, low dimensional, graded materials, we address the investigation of the energy (and spin) current in XXZ open…
The open Heisenberg chain under boundary fields: a magnonic logic gate
Gabriel T. Landi, Dragi Karevski
We study the spin transport in the quantum Heisenberg spin chain subject to boundary magnetic fields and driven out of equilibrium by Lindblad dissipators. An exact solution is giv…
Effect of diffusion in one-dimensional discontinuous absorbing phase transitions
Carlos E. Fiore, Gabriel T. Landi
It is known that diffusion provokes substantial changes in continuous absorbing phase transitions. Conversely, its effect on discontinuous transitions is much less understood. In o…
