Effects of boundary conditions on quantum nanoresonators: decoherence-free subspaces
Humberto C. F. Lemos, Thiago Cordeiro, Adelcio C. Oliveira
The Euler-Bernoulli beam model has been studied classically and semi-classically. The semi-classical quantization is done in an analogous way to the quantization of the electromagn…
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…
One-way street for the energy current: A ubiquitous phenomenon in boundary-driven quantum spin chains
Deborah Oliveira, Emmanuel Pereira, Humberto C F Lemos
Focusing on the description of nontrivial properties of the energy transport at quantum scale, we investigate asymmetrical quantum spin chains described by boundary-driven $\mathit…
Roughness as Classicality Indicator of a Quantum State
Humberto C. F. Lemos, Alexandre C. L. Almeida, Barbara Amaral +1
We define a new quantifier of classicality for a quantum state, the Roughness, which is given by the distance between Wigner and Husimi functions. We show th…
Convergence radius of perturbative Lindblad driven non-equilibrium steady states
Humberto C. F. Lemos, Tomaž Prosen
We address the problem of analyzing the radius of convergence of perturbative expansion of non-equilibrium steady states of Lindblad driven spin chains. A simple formal approach is…
