Abstract:

This project aimed to design and implement an experiment intended to stabilize and test a newly proposed state of matter the non-equilibrium Floquet topological metal. By performing electrical transport measurements while simultaneously propagating ultrasonic waves into the first known topological Kondo insulator, Samarium Hexaboride, we investigated the possibility of realizing a moving cascade of topological insulator-to-metal transitions to obtain bulk-like conduction through the Kondo insulator. Experiments in collaboration with Prof. T. Yanagisawa at Sapporo University, Japan, and Prof. T. McQueen at Johns Hopkins University resulted in a successful experimental observation of a positive effect. Further work is required to understand the origin of the anomalous effect of ultrasound propagation on electrical transport in SmB6.
