Quasi-solitons of the 1D Bose gas at arbitrary-strength contact repulsion
Anahita Sarvi, Cesare Vianello, Jean-Sébastien Caux
Harnessing integrability at arbitrary interaction strength, we build long-lived and spatially localized soliton-like excitations in the 1D Bose gas with contact repulsion (Lieb-Lin…
Discrete semiclassical theory of quantum-thermal escape
Luca Salasnich, Cesare Vianello
The dissipationless quantum-thermal escape rate from a metastable well is often written as a Boltzmann average of the Hill-Wheeler flux over a continuum of energies. This continuum…
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…
Dynamics of one-dimensional Bose-Josephson Junction in a Box Trap: From Coherent Oscillations to Many-Body Dephasing and Dynamical Freezing
Abhik Kumar Saha, L. F. Calazans de Brito, Cesare Vianello +4
Understanding how coherent quantum dynamics give way to correlation-dominated behavior in low-dimensional systems remains a central challenge in quantum many-body physics. Here, we…
Equilibrium and dynamical quantum phase transitions in dipolar atomic Josephson junctions
Cesare Vianello, Giovanni Mazzarella, Luca Salasnich
An atomic Josephson junction realized with dipolar bosons in a double-well potential can be described by an extended Bose-Hubbard model in which dipolar interactions generate an ef…
Coherent-state path integrals in quantum thermodynamics
Luca Salasnich, Cesare Vianello
In these notes, we elucidate some subtle aspects of coherent-state path integrals, focusing on their application to the equilibrium thermodynamics of quantum many-particle systems.…
Quantum action of the Josephson dynamics
Cesare Vianello, Sofia Salvatore, Luca Salasnich
We study the beyond-mean-field Josephson dynamics of the relative phase between two coupled macroscopic quantum systems. Using a covariant background field method, we derive the on…
Finite-temperature entanglement and coherence in asymmetric bosonic Josephson junctions
Cesare Vianello, Matteo Ferraretto, Luca Salasnich
We investigate the finite-temperature properties of a bosonic Josephson junction composed of N interacting atoms confined by a quasi-one-dimensional asymmetric double-well potentia…
Condensate and superfluid fraction of homogeneous Bose gases in a self-consistent Popov approximation
C. Vianello, L. Salasnich
We study the condensate and superfluid fraction of a homogeneous gas of weakly interacting bosons in three spatial dimensions by adopting a self-consistent Popov approximation, com…
