Quantum effective action for dissipative semiclassical dynamics
Cesare Vianello, Andrea Bardin, Luca Salasnich
Using the quantum effective action in the Schwinger-Keldysh formalism, we derive quantum-thermal corrections to the semiclassical dynamics of a dissipative system described by a ma…
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…
Repulsive fermions and shell effects on the surface of a sphere
Lorenzo Frigato, Andrea Bardin, Luca Salasnich
In recent years, ultracold atomic gases confined in curved geometries have attracted considerable theoretical interest. This is motivated by recent realizations of bubble traps in…
Quantum fluctuations in atomic Josephson junctions: the role of dimensionality
Andrea Bardin, Francesco Lorenzi, Luca Salasnich
We investigate the role of quantum fluctuations in the dynamics of a bosonic Josephson junction in spatial dimensions, by using beyond mean-field Gaussian corrections. We deriv…
