Description

In one-dimensional lattices with open boundaries, I will present a `fractal' structure high up in the energy specturm, and associated out-of-equilibrium consequences.
The non-equilibrium consequences are a hierarchy of `edge-locking' effects.
I will show versions of the phenomenon for three classic condensed-matter models:
(1) the Bose-Hubbard model;
(2) the spinless fermion model with nearest-neighbor repulsion;
(3) the XXZ (Heiseberg-Ising) spin chain.
