Abstract

A time evolution of quantum mechanical states by a time periodic Hamiltonian may contain extra information of topology in the time domain. As a result, there are examples of topological Floquet matter that are distinct from static counterparts. In this talk, I would like to introduce a time evolution operator that simulates the low energy physics of topological metal. The evolution comes with strong disorder mixing information in the quasi-energy domain. I will provide concrete numerical evidences testing the topological metallicity and simple experimental proposals identifying them.
