In 1D interacting lattice systems, I will present
geometry-induced structures in the energy specturm.
A dramatic series of dynamics-suppression effects arise due to these spectral structures.
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 spin chain. |
