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…
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…
Simple solutions of fireball hydrodynamics for self-similar elliptic flows
S. V. Akkelin, T. Csorgo, B. Lukacs +2
Simple, self-similar, elliptic solutions of non-relativistic fireball hydrodynamics are presented, generalizing earlier results for spherically symmetric fireballs with Hubble flow…
