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 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…
