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…
Determination of the critical exponents in dissipative phase transitions: Coherent anomaly approach
Jiasen Jin, Wen-Bin He, Fernando Iemini +4
We propose a generalization of the coherent anomaly method to extract the critical exponents of a phase transition occurring in the steady-state of an open quantum many-body system…
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…
Probing Genuine Multipartite Entanglement in Large Systems
Lucas B. Vieira, Diego L. Braga Ferreira, Thiago O. Maciel +1
We introduce a new kind of Entanglement Witness which is appropriate for studying genuine multipartite entanglement in large systems. The witness operator has a form that fits natu…
Completely Positive Maps for Reduced States of Indistinguishable Particles
Leonardo da Silva Souza, Tiago Debarba, Diego L. Braga Ferreira +2
We introduce a framework for the construction of completely positive maps for subsystems of indistinguishable fermionic particles. In this scenario, the initial global state is alw…
