Coupled-wire construction of static and Floquet second-order topological insulators
Raditya Weda Bomantara, Longwen Zhou, Jiaxin Pan +1
Second-order topological insulators (SOTI) exhibit protected gapless boundary states at their hinges or corners. In this paper, we propose a generic means to construct SOTIs in sta…
Non-Hermitian Floquet topological phases with arbitrarily many real-quasienergy edge states
Longwen Zhou, Jiangbin Gong
Topological states of matter in non-Hermitian systems have attracted a lot of attention due to their intriguing dynamical and transport properties. In this study, we propose a peri…
Recipe for creating an arbitrary number of Floquet chiral edge states
Longwen Zhou, Jiangbin Gong
Floquet states of periodically driven systems could exhibit rich topological properties. Many of them are absent in their static counterparts. One such example is the chiral edge s…
Floquet topological phases in a spin-1/2 double kicked rotor
Longwen Zhou, Jiangbin Gong
The double kicked rotor model is a physically realizable extension of the paradigmatic kicked rotor model in the study of quantum chaos. Even before the concept of Floquet topologi…
