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…
Theory and Experimental Investigation of the Quantum Valley Hall Effect
Kai Qian, David J. Apigo, Camelia Prodan +2
The quantum valley Hall effect (QVHE) has been observed in a variety of experimental setups, both quantum and classical. While extremely promising for applications, one should be r…
Topological Edge Modes by Smart Patterning
David Apigo, Kai Qian, Camelia Prodan +1
The research in topological materials and meta-materials reached maturity and is now gradually entering the phase of practical applications and devices. However, scaling down the e…
