Symmetry-protected topological corner modes in a periodically driven interacting spin lattice
Symmetry-protected topological corner modes in a periodically driven interacting spin lattice
Periodic driving has a longstanding reputation for generating exotic phases of matter with no static counterparts. This work explores the interplay between periodic driving, interaction effects, and ${\mathbb{Z}}_{2}$ symmetry that leads to the emergence of Floquet symmetry protected second-order topological phases in a simple but insightful two-dimensional spin-1/2 lattice.
