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…
Direct visualization of topological transitions and higher-order topological states in photonic metasurfaces
Anton Vakulenko, Svetlana Kiriushechkina, Mengyao Li +6
Topological photonic systems represent a new class of optical materials supporting boundary modes with unique properties, not found in conventional photonics. While the early resea…
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…
Photonic Higher-Order Topological States Induced by Long Range Interactions
Mengyao Li, Dmitry Zhirihin, Dmitry Filonov +4
The discovery of topological phases has recently led to a paradigm shift in condensed matter physics, and facilitated breakthroughs in engineered photonics and acoustic metamateria…
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…
