Ballistic-to-Localized Dynamics as Signature of Quantum Phase Transition in Josephson Junction
F. G. Capone, A. de Candia, G. Di Bello +5
Using state-of-the-art numerical techniques, we investigate how quantum phase fluctuations and quasiparticle tunneling shape the behavior of a small-capacitance Josephson junction…
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…
Quantum Brownian Motion: proving that the Schmid transition belongs to the Berezinskii-Kosterlitz-Thouless universality class
Francesco G. Capone, Antonio de Candia, Vittorio Cataudella +4
We investigate the equilibrium properties of a quantum Brownian particle moving in a periodic potential, specifically addressing the nature of the dissipation-driven Schmid transit…
Quantum vs thermal fluctuations in phase transitions of two-dimensional superconductors
Andrea Ponticelli, Francesco Giuseppe Capone, Vittorio Cataudella +3
We investigate the impact of quantum and thermal phase fluctuations on the suppression of superconducting order in two-dimensional systems. Within the two-dimensional quantum XY mo…
