Fourth-Order Topological Insulator via Dimensional Reduction
Kai Chen, Matthew Weiner, Mengyao Li +3
The properties of topological systems are inherently tied to their dimensionality. Higher-dimensional physical systems exhibit topological properties not shared by their lower dime…

Demonstration of a quantized acoustic octupole topological insulator
Xiang Ni, Mengyao Li, Matthew Weiner +2
Recently extended from the modern theory of electric polarization, quantized multipole topological insulators (QMTIs) describe higher-order multipole moments, lying in nested Wilso…

Demonstration of a 3rd order hierarchy of higher order topological states in a three-dimensional acoustic metamaterial
Matthew Weiner, Xiang Ni, Mengyao Li +2
In the past years classical wave-systems have constituted an excellent platform for emulating complex quantum phenomena. This approach has been especially fruitful in demonstrating…
