Non-Abelian physics in light and sound
Yi Yang, Biao Yang, Guancong Ma +3
There has been a recent surge of interest in using light and sound as platforms for studying non-Abelian physics. Through a kaleidoscope of physical effects, light and sound provid…
Experimental demonstration of non-adjacent band topology connecting multiple nodal links
Dongyang Wang, Biao Yang, Mudi Wang +5
Nodal links are special configurations of band degeneracies in the momentum space, where nodal line branches encircle each other. In PT symmetric systems, nodal lines can be topolo…
