Abstract
Recently, space-time group was proposed to describe the dynamic crystalline symmetries of a large class of dynamic systems beyond the Floquet system (Xu and Wu, Phys. Rev. Lett. 120, 096401 (2018)), including laser-driven solid crystals, dynamic photonic crystals, and optical lattices. We further study its consequences on physical observables on the response functions by applying the group theory representation analysis. This work will provide useful guidance for studying physical properties in time-dependent systems.
