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…
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…
Efficient simulation of a pair of dissipative qubits antiferromagnetically coupled
Francesco G. Capone, Giulio De Filippis, Vittorio Cataudella +1
We investigate the efficiency of different quantum Monte Carlo simulations of a pair of antiferromagnetically coupled qubits in an Ohmic dissipative environment. Using a Trotter-Su…
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…
