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…
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…
