Coupled-wire construction of non-Abelian higher-order topological phases
Jiaxin Pan, Longwen Zhou
Non-Abelian topological charges (NATCs), characterized by their noncommutative algebra, offer a framework for describing multigap topological phases beyond conventional Abelian inv…
Topological characterization of phase transitions and critical edge states in one-dimensional non-Hermitian systems with sublattice symmetry
Longwen Zhou, Rujia Jing, Shenlin Wu
Critical edge states appear at the bulk gap closing points of topological transitions. Their emergence signify the existence of topologically nontrivial critical points, whose desc…
Floquet Möbius topological insulators
Longwen Zhou, Fan Zhang, Jiaxin Pan
Möbius topological insulators have dispersive edge bands with Möbius twists in momentum space, which are protected by the combination of chiral and -projective translational s…
Observing the exponential growth of the eigenmodes in the absence of coalescence for a non-Hermitian circuit with an unavoidable inductor dissipation
Jiaming Zhang, Wenxuan Song, Hanhao Li +5
We investigate, both experimentally and theoretically, the eigenmodes of an electronic circuit in which gain and loss resonators are coupled through a capacitor. Due to the u…
Floquet non-Abelian topological charges and edge states
Jiaxin Pan, Longwen Zhou
Non-Abelian topological insulators are characterized by matrix-valued, non-commuting topological charges with regard to more than one energy gap. Their descriptions go beyond the c…
Gapless higher-order topology and corner states in Floquet systems
Longwen Zhou, Rongtao Wang, Jiaxin Pan
Higher-order topological phases (HOTPs) possess localized and symmetry-protected eigenmodes at corners and along hinges in two and three dimensional lattices. The numbers of these…
