Research Interests

I am interested in the numerical simulation of strongly-correlated quantum many-body systems with Tensor Networks and, in particular, in applying these methods to lattice field theories. Moreover, I also have a strong interest for quantum simulation of lattice field theories, and in using Tensor Network methods to assess the feasibility of such approaches for specific models and setups.
