Mirror skin effect and its electric circuit simulation
Tsuneya Yoshida, Tomonari Mizoguchi, Yasuhiro Hatsugai
Abstract
The authors discover the mirror skin effect, which highlights non-Hermitian topological properties protected by crystalline symmetry. Due to the mirror skin effect, the system shows a significant dependence of energy spectrum on the boundary condition only for the mirror invariant line in the two-dimensional Brillouin zone. They also propose how to experimentally observe the mirror skin effect by making use of high controllability of electric circuits.
