Personal profile
Research interests
My research expertise is on theoretical quantum light-matter physics and microcavity semiconductor heterostructures in the strong light-matter coupling regime, with a focus on exciton-polariton condensates. My investigations cover many-body topological Chern insulators, non-conservative vortex and soliton dynamics, dissipative spin lattice phases, artificial lattices and Bloch polaritons, fixed point and limit cycles attractor dynamics, spontaneous synchronization in oscillatory networks, and unconventional computing strategies based on polariton many-body physics.
