Experimental characterization of three-band braid relations in non-Hermitian acoustic lattices

Experimental characterization of three-band braid relations in non-Hermitian acoustic lattices

The nature of complex eigenenergy enables unique band topology in non-Hermitian (NH) lattices. Recently, there has been fast growing interest in the elusive winding and braiding topologies of the NH single and double bands, respectively. Here, we explore the even more intricate NH multiband topology...
