Certifying steady-state properties of open quantum systems
Luke Mortimer, Donato Farina, Grazia Di Bello +4
Estimating the steady-state properties of open many-body quantum systems is a fundamental challenge in quantum science and technologies. In this work, we present a scalable approac…

Local ergotropy and its fluctuations across a dissipative quantum phase transition
G. Di Bello, D. Farina, D. Jansen +3
We investigate a two-qubit open Rabi model, focusing on local ergotropy--the maximum extractable work by acting solely on the two qubits--within a parameter regime where a Berezins…

Environment induced dynamical quantum phase transitions in two-qubit Rabi model
G. Di Bello, A. Ponticelli, F. Pavan +4
The physics of quantum states beyond thermodynamic equilibrium represents a fascinating and cutting-edge research. Using numerical state-of-the-art approaches, we observe dynamical…
