The subject of study is the problem of formation of steady-state current in coherent quantum systems by homogeneous modulation of parameters. The purpose of the study is to control the dynamics of extremely "fragile" multi-particle quantum ensembles produced by the optical potentials of complex geometry and topology. Research methods are methods of quantum mechanics, statistical physics, and stochastic equations, numerical methods. Mechanisms of directional transport in systems with low dissipation and decoherence systems in both classical and quantum modes are investigated theoretically and experimentally. The theoretical results obtained were experimentally implemented to generate and control the directional motion of ensembles of cold cesium atoms and quantum ensembles of rubidium atoms cooled to Bose-Einstein condensation temperature. The results obtained are a qualitative and quantitative description of the new non-trivial effects arising in quantum-optical systems. They allow to control the dynamics of extremely "fragile" multi-particle quantum ensembles produced by the optical potentials of complex geometry and topology. The results obtained are relevant for solving problems in the field of quantum information processing, development of new technologies of precision quantum devices (gyroscopes, sensitive interferometers and ultra-fine timers), as well as open new perspectives for the idea of creating optical quantum chips, the so-called "all optical" atomic chips ».
