Abstract

We investigate charge relaxation in quantum wires of spinless disordered fermions (t-V model). Our observable is the time-dependent density propagator Pi(epsilon)(x.t), calculated in windows of different energy density epsilon of the many-body Hamiltonian and at different disorder strengths W, not exceeding the critical value W-c. The width Delta x(epsilon) (t) of Pi(epsilon)(x,t) exhibits a ...
