Relaxation of Double Occupancies in large U Hubbard Model

ORAL

Abstract

We study the relaxation rates of double occupancies in large U Fermionic Hubbard model both in the Mott insulating state and in the compressible state with holes. We find that the relaxation rate $\sim t exp(-U2/t2)$ in the insulating state and $\sim t exp(-U/t)$ in the compressible state.
