It is a conventional wisdom that the helical edge states of quantum spin Hall (QSH) insulator are particularly stable due to topological protection time-reversal symmetry. Here, we report first experimental observation an edge-dependent (pseudo-)spin effect by employing two Kekule electric circuits with molecule-zigzag and partially-bearded edges, where chirality circulating current in unit cel...

Monopoles play a center role in gauge theories and topological matter. There are two fundamental types of monopoles physics: vector tensor monopoles. Examples include the Dirac monopole three dimensions Yang five dimensions, which have been extensively studied observed condensed matter or artificial systems. However, less studied, their observation has not reported. Here we experimentally const...
