My Research Interests

My research focuses on the theory of strongly interacting quantum systems and their non-equilbirum dynamics. My important recent contribution has been to show that the photonic system strongly coupled to atoms can undergo a quantum phase transition away from the thermodynamical limit. In addition, motivated by the remarkable recent advances in tailoring the light-matter interaction beyond what is available in natural systems and building a large-scale photonic lattice device, I aim to develop a theory properly describing such a driven-dissipative many-body system and to identify new physical phenomena in this setting, and to contemplate its application for the quantum information science.
