Spectral analysis of equilibration: information leakage in isolated quantum systems
André T. Cesário, Marcos G. Alpino, Reinaldo O. Vianna +1
We develop a unified dynamical-spectral framework for equilibration in isolated quantum systems based on a subspace coarse-graining approach. Central to our formulation is the Leak…
A Complexity-Based Approach to Quantum Observable Equilibration
Marcos G. Alpino, Tiago Debarba, Reinaldo O. Vianna +1
We investigate the role of a statistical complexity measure to assign equilibration in isolated quantum systems. While unitary dynamics preserve global purity, expectation values o…
Quantum Interference of Force with Entangled Photons
Gabriela S. Militani, Artur Matoso, Denise F. Ávila +4
In this work we experimentally demonstrate the quantum interference of force effect using pairs of entangled photons. Although photons are massless particles, they have linear mome…
Quantum correlations, entanglement spectrum and coherence of two-particle reduced density matrix in the Extended Hubbard Model
Diego L. B. Ferreira, Thiago O. Maciel, Reinaldo O. Vianna +1
We study the ground state properties of the one-dimensional extended Hubbard model at half-filling from the perspective of its particle reduced density matrix. We focus on the redu…
Simple and maximally robust processes with no classical common-cause or direct-cause explanation
Marcello Nery, Marco Túlio Quintino, Philippe Allard Guérin +2
Guided by the intuition of coherent superposition of causal relations, recent works presented quantum processes without classical common-cause and direct-cause explanation, that is…
Quantum Statistical Complexity Measure as a Signalling of Correlation Transitions
André T. Cesário, Diego L. B. Ferreira, Tiago Debarba +3
We introduce a quantum version for the statistical complexity measure, in the context of quantum information theory, and use it as a signalling function of quantum order-disorder t…
