Spectra, eigenstates and transport properties of a -symmetric ring
Adrian Ortega, Luis Benet, Hernán Larralde
We study, analytically and numerically, a simple -symmetric tight-binding ring with an onsite energy at the gain and loss sites. We show that if , the sy…
Spectral and transport properties of a -symmetric tight-binding chain with gain and loss
Adrian Ortega, Thomas Stegmann, Luis Benet +1
We derive a continuity equation to study transport properties in a -symmetric tight-binding chain with gain and loss in symmetric configurations. This allows us to id…
Two-particle quantum correlations in stochastically-coupled networks
Roberto de J. León-Montiel, Vicenç Méndez, Mario A. Quiroz-Juárez +4
Quantum walks in dynamically-disordered networks have become an invaluable tool for understanding the physics of open quantum systems. In this work, we introduce a novel approach t…
Robustness of optimal transport in disordered interacting many-body networks
Adrian Ortega, Thomas Stegmann, Luis Benet
The robustness of quantum transport under various perturbations is analyzed in disordered interacting many-body systems, which are constructed from the embedded Gaussian random mat…
Efficient quantum transport in disordered interacting many-body networks
Adrian Ortega, Thomas Stegmann, Luis Benet
The coherent transport of fermions in disordered networks of single-particle states connected by -body interactions is studied. These networks are modeled by embedded Ga…
Quantum efficiencies in finite disordered networks connected by many-body interactions
Adrian Ortega, Manan Vyas, Luis Benet
The quantum efficiency in the transfer of an initial excitation in disordered finite networks, modeled by the -body embedded Gaussian ensembles of random matrices, is studied fo…
