Dynamic Topological Light Control in Reconfigurable Non-Hermitian Metastacks
Ryan Hogan, Zihan Lu, Han Peng +4
Metasurfaces often require complex lithography for dynamic optical control. To overcome this, we utilize a lithography-free, non-Hermitian planar metastack comprising a distributed…

Topological Degeneracy Induced by Twisting
Han Peng, Qiang Wang, Meng Xiao +3
In recent years, twisting has emerged as a new degree of freedom that plays an increasingly important role in Bloch bands of various physical systems. However, there is currently a…
