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…

Hermitian and non-Hermitian topology in active matter

Kazuki Sone, Kazuki Yokomizo, Kyogo Kawaguchi +1

Self-propulsion is a quintessential aspect of biological systems, which can induce nonequilibrium phenomena that have no counterparts in passive systems. Motivated by biophysical i…

Bulk-Boundary Correspondence in Ergodic and Nonergodic One-Dimensional Stochastic Processes

Taro Sawada, Kazuki Sone, Kazuki Yokomizo +2

Bulk-boundary correspondence is a fundamental principle in topological physics. In recent years, there have been considerable efforts in extending the idea of geometry and topology…

Transition from topological to chaos in the nonlinear Su-Schrieffer-Heeger model

Kazuki Sone, Motohiko Ezawa, Zongping Gong +3

Recent studies on topological materials are expanding into the nonlinear regime, while the central principle, namely the bulk-edge correspondence, is yet to be elucidated in the st…

Nonlinearity-induced topological phase transition characterized by the nonlinear Chern number

Kazuki Sone, Motohiko Ezawa, Yuto Ashida +2

As first demonstrated by the characterization of the quantum Hall effect by the Chern number, topology provides a guiding principle to realize robust properties of condensed matter…
