TL;DR

This paper demonstrates how spatially-modulated light can generate and manipulate localized bulk modes in Floquet topological insulators, with potential applications across various material systems including graphene and zincblende structures.

Contribution

It introduces a method to control bulk localized modes in Floquet topological insulators using light modulation, extending previous work to new properties and three-dimensional systems.

Findings

Localized modes can be generated via light phase, polarization, and frequency modulation.

The approach applies to systems like graphene and zincblende models.

Results are generalized to three-dimensional topological insulators.

Abstract

We investigate Floquet Topological Insulators in the presence of spatially-modulated light. We extend on previous work to show that light can be used to generate and control localized modes in the bulk of these systems. We provide examples of bulk modes generated through modulation of different properties of the light, such as its phase, polarization and frequency. We show that these effects may be realized in a variety of systems, including a zincblende model and graphene, and also provide a generalization of these results to three dimensional systems.
