Hierarchy of edge-locking effects in one-dimensional quantum lattice models. — •Masud Haque — MPI-PKS, Dresden

In one-dimensional lattices with open boundary conditions, I will present a hierarchy of edge-locking (or edge localization) 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 spin chain.

The edge-locking effects will be demonstrated through far-from-equilibrium dynamics and spectral characteristics far from the ground state.
