Uhlmann Fidelity and Fidelity Susceptibility for Integrable Spin Chains at Finite Temperature: Exact Results

Michał Białończyk, Fernando Javier Gómez-Ruiz, Adolfo del Campo

We derive the exact expression for the Uhlmann fidelity between arbitrary thermal Gibbs states of the quantum XY model in a transverse field with finite system size. Using it, we c…

Universal Statistics of Vortices in a Newborn Holographic Superconductor: Beyond the Kibble-Zurek Mechanism

Adolfo del Campo, Fernando Javier Gómez-Ruiz, Zhi-Hong Li +3

Traversing a continuous phase transition at a finite rate leads to the breakdown of adiabatic dynamics and the formation of topological defects, as predicted by the celebrated Kibb…

Quantum Non-equilibrium Many-Body Spin-Photon Systems

Fernando J. Gómez-Ruiz

In this Ph.D. thesis dissertation concerns the quantum dynamics of strongly-correlated quantum systems in out-of-equilibrium states. The research is neither restricted to static pr…

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…

Probing the Universality of Topological Defect Formation in a Quantum Annealer: Kibble-Zurek Mechanism and Beyond

Yuki Bando, Yuki Susa, Hiroki Oshiyama +7

The number of topological defects created in a system driven through a quantum phase transition exhibits a power-law scaling with the driving time. This universal scaling law is th…

Dynamics of Entanglement and the Schmidt Gap in a Driven Light-Matter System

F. J. Gómez-Ruiz, J. J. Mendoza-Arenas, O. L. Acevedo +3

The ability to modify light-matter coupling in time (e.g. using external pulses) opens up the exciting possibility of generating and probing new aspects of quantum correlations in…
