Topological pump and its plateau transitions of -leg spin ladder
Kota Yamamoto, Yoshihito Kuno, Tomonari Mizoguchi +2
A topological pump on an leg spin ladder is discussed by introducing spatial clusterization whose adiabatic limit is a set of site staircase clusters. We…

Topological-to-Topological Transition Induced by On-Site Nonlinearity in a One-Dimensional Topological Insulator
Kazuki Sone, Yasuhiro Hatsugai
Recent studies have extended the notion of band topology to nonlinear systems by defining nonlinear counterparts of eigenvalue problems. They have found the nonlinearity-induced to…
