Abstract

In 2018, Frank Wilczek and I proposed the concept of “quantum atmosphere”. The quantum atmosphere promises a new way to probe symmetries and topological information of materials. The feasibility of our proposal has been demonstrated by a recent experiment. In this talk, I will explain the concept of quantum atmosphere and describe how it emerges from our study of the Casimir effect.
