Título: "Quantum walk on an interacting graph and statistical physics"

Dr. Alberto Verga de Aix-Marseille Université
 
Abstract: 
We propose a simple model of an interacting quantum system showing thermalization. A particle jumps between the nodes of a graph defined by a set of spins. Couplings are essentially swapping amplitudes between internal and position degrees of freedom. Depending on the graph topology and symmetries, the particle position distributes according to the microcanonical ensemble, and the spins relax to a paramagnetic state. The relation of these macroscopic properties with random matrices ensembles and interaction generated entanglement is discussed.
