Experimental Realization of Two-Dimensional Weak Topological Insulators

Experimental Realization of Two-Dimensional Weak Topological Insulators

We report the experimental realization of a two-dimensional (2D) weak topological insulator (WTI) in spinless Su-Schrieffer-Heeger circuits with parity-time and chiral symmetries. Strong and weak Z2 topological indexes are adopted to explain the experimental findings that a Dirac semimetal (DSM) pha...
