Ideal Bose-Einstein condensation in the canonical ensemble: exact asymptotic estimates from large deviations
Giacomo Gradenigo, Dario Lucente, Luca Salasnich
In this work we present a large-deviations approach to the calculation of the canonical partition function for free bosons. Three-dimensional Bose-Einstein condensation is studied…
Quantum corrections to the Josephson dynamics: a population-imbalance approach
Oliver Hideg, Sofia Salvatore, Luca Salasnich
We investigate quantum corrections to the Josephson dynamics of two weakly coupled Bose-Einstein condensates using the population imbalance as the sole dynamical variable. Starting…
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…
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…
Effective action approach to quantum and thermal effects: from one particle to Bose-Einstein condensates
Luca Salasnich
We present a detailed derivation of the quantum and quantum-thermal effective action for non-relativistic systems, starting from the single particle case and extending to the Gross…
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.…
Entropy production and irreversibility in the linearized stochastic Amari neural model
Dario Lucente, Giacomo Gradenigo, Luca Salasnich
One among the most intriguing results coming from the application of statistical mechanics to the study of brain is the understanding that it, as a dynamical system, is inherently…
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…
Interaction between gravitational waves and trapped Bose-Einstein condensates
A. Perodi, L. Salasnich
Inspired by recent proposals for detecting gravitational waves by using Bose-Einstein condensates (BECs), we investigate the interplay between these two phenomena. A gravitational…
Solitons in Quasiperiodic Lattices with Fractional Diffraction
Eduard Pavlyshynets, Luca Salasnich, Boris A. Malomed +1
We study the dynamics of solitons under the action of one-dimensional quasiperiodic lattice potentials, fractional diffraction, and nonlinearity. The formation and stability of the…
Quantum Vortices in Curved Geometries
A. Tononi, L. Salasnich, A. Yakimenko
The control over the geometry and topology of quantum systems is crucial for advancing novel quantum technologies. This work provides a synthesis of recent insights into the behavi…
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…
Symplectic quantization III: Non-relativistic limit
Giacomo Gradenigo, Roberto Livi, Luca Salasnich
First of all we shortly illustrate how the symplectic quantization scheme [Gradenigo and Livi, 2021] can be applied to a relativistic field theory with self-interaction. Taking ins…
Electrodynamics of superconductors: from Lorentz to Galilei at zero temperature
Luca Salasnich
We discuss the derivation of the electrodynamics of superconductors coupled to the electromagnetic field from a Lorentz-invariant bosonic model of Cooper pairs. Our results are obt…
