Local and Global Master Equations through the Lens of Non-Hermitian Physics
Grazia Di Bello, Fabrizio Pavan, Vittorio Cataudella +1
We investigate the relation between non-Hermitian Hamiltonian and Lindblad dynamics in nonequilibrium open quantum systems. Non-Hermitian models can extend phase diagrams and enabl…
Kibble-Zurek Mechanism in the Open Quantum Rabi Model
T. Pirozzi, G. Di Bello, V. Cataudella +2
The Kibble-Zurek mechanism provides a universal framework for predicting defect formation in non-equilibrium phase transitions. While Markovian dissipation typically degrades unive…
Charging power enhancement at the phase transition of a non-integrable quantum battery
D. Farina, M. Sassetti, V. Cataudella +2
Exploiting many-body interaction and critical phenomena to improve the performance of quantum batteries is an emerging and promising line of research. A central question in this di…
Local ergotropy dynamically witnesses many-body localized phases
Francesco Formicola, Grazia Di Bello, Giulio De Filippis +3
Many-body localization is a dynamical phenomenon characteristic of strongly interacting and disordered many-body quantum systems which fail to achieve thermal equilibrium. From a q…
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…
