Charge and spin qubits in interacting quantum dots coupled to Rashba-active leads
Grazia Di Bello, Fabrizio Pavan, Mattia Trama +3
We present a unified study of charge and spin qubits encoded in a single interacting quantum dot tunnel-coupled to Rashba fermionic leads. The dot is described by an Anderson impur…
Dynamical Crossover of the Quantum Fisher Information in the Spin-Boson Model
D. Parlato, G. Di Bello, F. Pavan +2
We investigate the dynamical quantum Fisher information of a two-level system coupled to a bosonic environment, focusing on the estimation of the qubit gap. We combine analytical c…
Discrete time crystals in disordered anisotropic Heisenberg chains
Francesco Formicola, Grazia Di Bello, Antonio De Candia +2
A discrete time crystal is an out-of-equilibrium phase of matter characterized by the spontaneous breaking of discrete time-translation symmetry. Using extensive numerical simulati…
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…
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…
Bloch sphere picture and restoration of the quantum Mpemba effect beyond the weak coupling regime in the spin boson model
P. Chirico, G. Di Bello, G. De Filippis +1
Understanding relaxation dynamics in open quantum systems is a central problem in nonequilibrium quantum physics. Here we investigate the quantum Mpemba effect in the spin boson mo…
