Project is devoted to research on quantum simulators of open-quantum systems and non-equilibrium topological matter realized in quantum gases and photonic structures.
Understanding the behavior of topological properties of quantum systems out-of-equilibrium remains one of the central challenges in condensed-matter physics. On the experimental level main challenge is to construct quantum Simulators where full control of coherent dynamics and dissipative processes is possible, allowing to study non-equilibrium quantum states. Presented project focus on possibilities of realizing Quantum Simulators for open quantum systems allowing to study non-equilibrium topological phenomena. One of the main objectives of the proposal is to theoretically study quantum system dynamics after a sudden change of its topological invariant. The other main Objective is the study dissipation-driven evolution of the quantum system, which eventually leads to a non-trivial topological state, where coherent dynamics and dissipation interplay. Both objectives aim to break new ground by significantly expanding concepts of equilibrium topological matter.
Project title: Effects of Anderson localization in ultracold quantum gases
Time span: 12.2011 - 12.2014

The project was devoted to research on Anderson localization of matter waves in an optical random potential. The project was related to the experimental results where matter-waves Anderson localization in the non-interacting Bose-Einstein condensate was observed (Nature 453, 891 2008). In this project I focused on studying influence of interactions on Anderson localization of a Bose-Einstein condensate in soliton state, in particular:
a) Dynamics of interacting bright solitons in the random potential
b) Experimental constraints on the observation of Anderson's location of the dark soliton, including estimating its lifetime in a random potential
c) Comparing the predictions of the modified mean-field description with multi-body accounts based on the matrix product states ansatz.
