Two-mode Bose gas: Beyond classical squeezing — •Cédric Bodet and Thomas Gasenzer — Institut für Theoretische Physik, Universität Heidelberg, Philosophenweg 16, 69120 Heidelberg

The dynamical evolution of squeezing correlations in an ultracold Bose-Einstein distributed across two modes is investigated theoretically in the framework of the Bose-Hubbard model. We study the development of non-classical correlations and relative number squeezing in regimes where the system is strongly interacting. Comparing the full quantum evolution with classical statistical simulations allows to identify quantum aspects of the squeezing formation. In the quantum regime, the measurement of squeezing allows to distinguish even and odd total particle numbers.
