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…

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…
