Floquet topological phases with fourfold-degenerate edge modes in a driven spin-1/2 Creutz ladder
Longwen Zhou, Qianqian Du
Floquet engineering has the advantage of generating new phases with large topological invariants and many edge states by simple driving protocols. In this work, we propose an appro…
Non-Hermitian Floquet topological superconductors with multiple Majorana edge modes
Longwen Zhou
Majorana edge modes are candidate elements of topological quantum computing. In this work, we purpose a Floquet engineering approach to generate arbitrarily many non-Hermitian Majo…
Dynamical characterization of non-Hermitian Floquet topological phases in one-dimension
Longwen Zhou
Non-Hermitian topological phases in static and periodically driven systems have attracted great attention in recent years. Finding dynamical probes for these exotic phases would be…
Non-Hermitian Floquet topological phases in the double-kicked rotor
Longwen Zhou, Jiaxin Pan
Dynamical kicking systems possess rich topological structures. In this work, we study Floquet states of matter in a non-Hermitian extension of double kicked rotor model. Under the…
Revealing many-body effects on interband coherence through adiabatic charge pumping
Sen Mu, Da-Jian Zhang, Longwen Zhou +1
The adiabatic charge pumping of a non-equilibrium state of spinless fermions in a one-dimensional lattice is investigated, with an emphasis placed on its usefulness in revealing ma…
Floquet dynamical quantum phase transitions
Kai Yang, Longwen Zhou, Wenchao Ma +8
Dynamical quantum phase transitions (DQPTs) are manifested by time-domain nonanalytic behaviors of many-body systems.Introducing a quench is so far understood as a typical scenario…
