Characterisation of the dynamical quantum state of a zero temperature Bose-Einstein condensate
نویسنده
چکیده
We describe the quantum state of a Bose-Einstein condensate at zero temperature. By evaluating the Q-function we show that the ground state of Bose-Einstein condensate under the Hartree approximation is squeezed. We find that multimode Schrödinger cat states are generated as the condensate evolves in a ballistic expansion.

Solitons for nearly integrable bright spinor Bose-Einstein condensate
Using the explicit forms of eigenstates for linearized operator related to a matrix version of Nonlinear Schrödinger equation, soliton perturbation theory is developed for the $F=1$ bright spinor Bose-Einstein condensates. A small disturbance of the integrability condition can be considered as a small correction to the integrable equation. By choosing appropriate perturbation, the soli...
متن کاملImpurities as a quantum thermometer for a Bose-Einstein condensate
We introduce a primary thermometer which measures the temperature of a Bose-Einstein Condensate in the sub-nK regime. We show, using quantum Fisher information, that the precision of our technique improves the state-of-the-art in thermometry in the sub-nK regime. The temperature of the condensate is mapped onto the quantum phase of an atomic dot that interacts with the system for short times. W...
متن کاملSemiclassical Corrections to a Static Bose-Einstein Condensate at Zero Temperature
In the mean-field approximation, a trapped Bose-Einstein condensate at zero temperature is described by the Gross-Pitaevskii equation for the condensate, or equivalently, by the hydrodynamic equations for the number density and the current density. These equations receive corrections from quantum field fluctuations around the mean field. We calculate the semiclassical corrections to these equat...
متن کاملQuantum Corrections to a Static Bose-Einstein Condensate at Zero Temperature
A previous calculation of the leading corrections from quantum field fluctuations to the ground state of a trapped Bose-Einstein condensate at zero temperature is extended to general time-independent states, including vortex states. The calculation is streamlined by using dimensional regularization to regularize both ultraviolet and infrared divergences. We calculate the leading quantum correct...
متن کاملBose-Einstein Condensation in Exotic Trapping Potentials
We discuss thermal and dynamical properties of Bose condensates confined by an external potential. First we analyze the Bose-Einstein transition temperature for an ideal Bose gas in a generic power-law potential and d-dimensional space. Then we investigate the effect of the shape of the trapping potential on the properties of a weakly-interacting Bose condensate. We show that using exotic trapp...
