Non-ergodic states induced by impurity levels in quantum spin chains
A. O. García Rodríguez, G. G. Cabrera
The semi-infinite XY spin chain with an impurity at the boundary has been chosen as a prototype of interacting many-body systems to test for non-ergodic behavior. The model is exac…

Preparation of non-ergodic states in quantum spin chains
A. O. García Rodríguez, G. G. Cabrera
We test the time evolution of quite general initial states in a model that is exactly solvable, a semi-infinite spin chain with an impurity at the boundary. The dynamic…
