Research Interests

I am interested in the interplay between quantum information and statistical and non-equilibrium physics, with a focus on methods inspired by the framework of resource theories.

This includes questions such as:

-Can we use the technical tools from quantum information to characterize the out of equilibrium fluctuations of quantum systems?

-How do statistical or thermal ensembles, as well as dissipation, emerge from the unitary dynamics of many body systems?

-What are the fundamental limitations of cooling quantum systems? Can were construct optimal cooling protocols?

-What is the role of different quantum resources, such as entanglement and of coherence, in the non-equilibrium physics of small systems?
