Non-Equilibrium Mass Transport in the 1D Fermi-Hubbard Model
We experimentally and numerically investigate the sudden expansion of
fermions in a homogeneous one-dimensional optical lattice. For initial states
with an appreciable amount of doublons, we observe a dynamical phase separation
between rapidly expanding singlons and slow doublons remaining in the trap
center, realizing the key aspect of fermionic quantum distillation in the
strongly-interacting limit. For initial states without doublons, we find a
reduced interaction dependence of the asymptotic expansion speed compared to
bosons, which is explained by the interaction energy produced in the quench
