Rényi Entropy Singularities as Signatures of Topological Criticality in Coupled Photon-Fermion Systems
F. P. M. Méndez-Córdoba, J. J. Mendoza-Arenas, F. J. Gómez-Ruiz +3
We show that the topological phase transition for a Kitaev chain embedded in a cavity can be identified by measuring experimentally accessible photon observables such as the Fano f…
Enhancing violations of Leggett-Garg inequalities in nonequilibrium correlated many-body systems by interactions and decoherence
J. J. Mendoza-Arenas, F. J. Gómez-Ruiz, F. J. Rodríguez +1
We identify different schemes to enhance the violation of Leggett-Garg inequalities in open many-body systems. Considering a nonequilibrium archetypical setup of quantum transport,…
Chapter: Vulnerability of Quantum Information Systems to Collective Manipulation
Fernando J. Gómez-Ruiz, Ferney J. Rodríguez, Luis Quiroga +1
The highly specialist terms `quantum computing' and `quantum information', together with the broader term `quantum technologies', now appear regularly in the mainstream media. Whil…
Universal two-time correlations, out-of-time-ordered correlators and Leggett-Garg inequality violation by edge Majorana fermion qubits
F. J. Gomez-Ruiz, J. J. Mendoza-Arenas, F. J. Rodriguez +2
In the present work we propose that two-time correlations of Majorana edge localized fermions constitute a novel and versatile toolbox for assessing the topological phases of 1D op…
Energy transfer in -component nanosystems enhanced by pulse-driven vibronic many-body entanglement
Fernando J. Gómez-Ruiz, Oscar L. Acevedo, Ferney J. Rodríguez +2
The processing of energy by transfer and redistribution plays a key role in the evolution of dynamical systems. At the ultrasmall and ultrafast scale of nanosystems, quantum cohere…
Pulsed Generation of Quantum Coherences and Non-classicality in Light-Matter Systems
F. J. Gomez-Ruiz, O. L. Acevedo, F. J. Rodriguez +2
We show that a pulsed stimulus can be used to generate many-body quantum coherences in light-matter systems of general size. Specifically, we calculate the exact real-time evolutio…
