Macroscopic Irreversibility in Quantum Systems: Free Expansion in a Fermion Chain
In a free fermion chain, the coarse-grained density distribution becomes almost uniform at sufficiently large typical times for any initial state with fixed macroscopic particle number, proving macroscopic irreversibility from unitary evolution.
