Topological phases and nonreciprocal edge states in non-Hermitian Floquet Insulators
Mengyao Li, Xiang Ni, Matthew Weiner +2
Topological phases in quantum and classical systems have been of significant recent interest due to their fascinating physical properties. While a range of different mechanisms to…

Observation of Bulk Polarization Transitions and Higher-Order Embedded Topological Eigenstates for Sound
Xiang Ni, Matthew Weiner, Andrea Alù +1
Topological systems are inherently robust to disorder and continuous perturbations, resulting in dissipation-free edge transport of electrons in quantum solids, or reflectionless g…
