Generating many Majorana corner modes and multiple phase transitions in Floquet second-order topological superconductors
Longwen Zhou
A -dimensional, th-order topological insulator or superconductor has localized eigenmodes at its -dimensional boundaries (). In this work, we apply periodic d…
Observation of Floquet topological phases with large Chern numbers
Kai Yang, Shaoyi Xu, Longwen Zhou +7
One of the most intriguing advantage of Floquet engineering is to generate new phases with large topological invariants. In this work, we experimentally simulate a periodically que…
Floquet band engineering with Bloch oscillations
Xi Liu, Senmao Tan, Qing-hai Wang +2
This work provides a convenient and powerful means towards the engineering of Floquet bands via Bloch oscillations, by adding a tilted linear potential to periodically driven latti…
Entanglement spectrum and entropy in Floquet topological matter
Longwen Zhou
Entanglement is one of the most fundamental features of quantum systems. In this work, we obtain the entanglement spectrum and entropy of Floquet noninteracting fermionic lattice m…
Engineering Floquet Dynamical Quantum Phase Transition
J. Naji, R. Jafari, Longwen Zhou +1
Floquet dynamical quantum phase transitions (FDQPTs) are signified by recurrent nonanalytic behaviors of observables in time. In this work, we introduce a quench-free and generic a…
th-root non-Hermitian Floquet topological insulators
Longwen Zhou, Raditya Weda Bomantara, Shenlin Wu
Floquet phases of matter have attracted great attention due to their dynamical and topological nature that are unique to nonequilibrium settings. In this work, we introduce a gener…
Driving-induced multiple -symmetry breaking transitions and reentrant localization transitions in non-Hermitian Floquet quasicrystals
Longwen Zhou, Wenqian Han
The cooperation between time-periodic driving fields and non-Hermitian effects could endow systems with distinctive spectral and transport properties. In this work, we uncover an i…
