Bosonic Josephson junction dynamics: interplay between quantum and thermal fluctuations
Andrea Bardin, Francesco Lorenzi, Luca Salasnich
We investigate the superfluid dynamics of a Josephson junction beyond the mean-field description, incorporating the role of thermal fluctuations as well as quantum fluctuations. Us…

Macroscopic quantum self-trapping in bosonic Josephson junctions: an exact quantum treatment
Andrea Bardin, Anna Minguzzi, Luca Salasnich
We investigate the fully quantum evolution of the population imbalance in a perfectly symmetric Bose-Josephson junction modeled by a two-mode Bose-Hubbard Hamiltonian, focusing on…
