Quantum Hall criticality in Floquet topological insulators

Topological Floquet Anderson Insulators (TFAIs) are systems in which an interplay of topology, driving, and static disorder stabilizes a unique form of topological quantum matter. Here, the authors present a first-principles theory, describing the topological phases and quantum criticality of the two-dimensional TFAIs in symmetry class A. Within this framework, they demonstrate how disorder is key to the formation of topological quantization, and that its critical behavior is in the quantum Hall universality class.
