Revealing Topology in Metals using Experimental Protocols Inspired by -Theory
Wenting Cheng, Alexander Cerjan, Ssu-Ying Chen +3
Topological metals are special conducting materials with gapless band structures and nontrivial edge-localized resonances, whose discovery has proved elusive because the traditiona…
Revealing the boundary Weyl physics of the four-dimensional Hall effect via phason engineering in metamaterials
Wenting Cheng, Emil Prodan, Camelia Prodan
Quantum Hall physics has been theoretically predicted in 4-dimensions and higher. In hypothetical 2n-dimensions, the topological characters of both the bulk and the boundary are ma…
Experimental Demonstration of Dynamic Topological Pumping Across Incommensurate Bilayered Acoustic Metamaterials
Wenting Cheng, Emil Prodan, Camelia Prodan
A Thouless pump can be regarded as a dynamical version of the integer quantum Hall effect. In a finite-size configuration, such topological pump displays edge modes that emerge dyn…
Observation of topological edge modes in a quasi-periodic acoustic waveguide
David J. Apigo, Wenting Cheng, Kyle F. Dobiszewski +2
Topological boundary and interface modes are generated in an acoustic waveguide by simple quasi-periodic patternings of the walls. The procedure opens many topological gaps in the…
