Without being confined to particular subjects or limited to specific approaches, I am interested in all physics that uncovers the truth and beauty of Nature. So far my focus has been on the understanding of quantum phases of matter and the transitions between them, with special focus on quantum criticality. Recently I have also started working on non-equilibrium many-body physics and gravity.
