Реферат:	eng: The feedback control scheme for a Bose-Einstein condensate (BEC) in a double-well trapping potential located in one arm of Mach-Zehnder interferometer (MZI) is investigated. The off-resonant light beam performs the phase probing in one of the wells, thus creating information about the number of atoms in this well. The parameters of the trapping potential are controlled via a feedback loop based on the measured output of the MZI. The problem is analyzed in the framework of master equations for hybrid quantum-classical systems. Significant modifications of the stationary distribution of atoms over the wells are predicted. These distributions can effectively be controlled by the tunable phase shift in the other arm of the MZI.
