A single-particle dark state in a dissipating spin chain induces universal long-time many-body dynamics with momentum distribution scaling as k sqrt(t) and density decaying as 1/(sqrt(t) log t).
Since both ˆck fork∈Z ap and ˆcp forp∈Z p span the one-particle Hilbert space on a ring, they can be related to each other

Universal dynamics from a single-particle dark state
A single-particle dark state in a dissipating spin chain induces universal long-time many-body dynamics with momentum distribution scaling as k sqrt(t) and density decaying as 1/(sqrt(t) log t).
