I am a theoretical condensed matter physicist dealing with problems at the intersection of atomic physics, quantum optics, photonics, solid state physics and bio-physics.
My main field of interest is the theory of ultracold quantum gases, where I work at understanding and engineering novel states of matter. My current research aims at studying static and out-of-equilibrium properties of magnetic, superfluid, topological, and strongly-interacting phases. To address this challenging physics, I attack problems from both the few-body and the many-body sides, using mostly diagrammatic techniques and variational Ansätze.
Most recently, I focused specifically on models with non-trivial topological features implemented in ultracold atoms, as well as in photonic, polaritonic and other condensed matter setups. I am also actively investigating quasiparticle physics, superfluid vortex dynamics, together with intriguing effects generated by periodic-driving, strong losses and disorder.
