Research Interests

I'm a condensed matter physicist working on strongly correlated quantum systems on the lattice and in the continuum, using
numerical tools like tensor network methods. In particular, I'm interested in out of equilibrium dynamics of low dimensional quantum systems, like e.g. spin chains or interacting impurities coupled to fermionic or bosonic reservoirs.
I have also a strong interest in tensor networks for continuous quantum field theories, where I develop methods for ground state
and excited state optimization.
