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…
Exact Delta Kick Cooling, Time-Optimal Control of Scale-Invariant Dynamics, and Shortcuts to Adiabaticity Assisted by Kicks
Léonce Dupays, David C. Spierings, Aephraim M. Steinberg +1
Delta kick cooling (DKC) is used to compress the momentum distribution of ultracold quantum matter. It combines expansion dynamics with the use of kick pulses, designed via classic…
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…
Thermofield dynamics: Quantum Chaos versus Decoherence
Zhenyu Xu, Aurelia Chenu, Tomaž Prosen +1
Quantum chaos imposes universal spectral signatures that govern the thermofield dynamics of a many-body system in isolation. The fidelity between the initial and time-evolving ther…
Exact ground states of quantum many-body systems under confinement
Adolfo del Campo
Knowledge of the ground state of a homogeneous quantum many-body system can be used to find the exact ground state of a dual inhomogeneous system with a confining potential. For th…
Universal finite-time thermodynamics of many-body quantum machines from Kibble-Zurek scaling
Revathy B. S., Victor Mukherjee, Uma Divakaran +1
We demonstrate the existence of universal features in the finite-time thermodynamics of quantum machines by considering a many-body quantum Otto cycle in which the working medium i…
