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 engineering of topological localization transitions and mobility edges in one-dimensional non-Hermitian quasicrystals
Longwen Zhou
Time-periodic driving fields could endow a system with peculiar topological and transport features. In this work, we find dynamically controlled localization transitions and mobili…
Non-Hermitian quasicrystal in dimerized lattices
Longwen Zhou, Wenqian Han
Non-Hermitian quasicrystals possess PT and metal-insulator transitions induced by gain and loss or nonreciprocal effects. In this work, we uncover the nature of localization transi…
Non-Hermitian topological phases and dynamical quantum phase transitions: A generic connection
Longwen Zhou, Qianqian Du
The dynamical and topological properties of non-Hermitian systems have attracted great attention in recent years. In this work, we establish an intrinsic connection between two cla…
Floquet higher-order topological phases in momentum space
Longwen Zhou
Higher-order topological phases (HOTPs) are characterized by symmetry-protected bound states at the corners or hinges of the system. In this work, we reveal a momentum-space counte…
