My research interests

My main interest in physics is the study of open quantum systems out of equilibrium. In general, these are driven quantum systems that are not allowed to equilibrate with their environments. In the recent years new questions about these systems has been posed by physicists from different sub-specializations. They span a large range, from the requirement of new laws for stochastic (and microscopic) thermodynamics to the need of new universality classes in macroscopic phases of matter and their phase transitions.

My current research is focused on how a time crystal, a recently discovered phase of matter, can be formed in a driven and dissipative setup. We have recently showed that a Bose-Hubbard dimer, a minimal quasi-zero-dimensional quantum system, can form a bistable time crystal when two modes are collectively driven and dissipated. We are currently exploring how this phenomena can be generalized to other, possibly more complicated, systems.

You can find all my works in google scholar.
