In Floquet topological systems the two-terminal conductance quantizes to |W_ε| e²/h and the Hall conductance to W_ε e²/h after summing all Floquet sidebands, where W_ε is the winding invariant of the quasienergy gap.

Uniaxial strain and obliquely incident circularly polarized light stabilize a Floquet second-order topological insulator in graphene featuring gapped edges and robust corner modes.
Integrated left-right transmission asymmetry in open Floquet lattices saturates to the bulk winding number via unit population of propagating Floquet-Bloch branches.
Periodic driving of the SSH model with two unitaries produces end modes whose count can mismatch the winding number, while quasiperiodic protocols yield Loschmidt echoes that oscillate near one for long times before decaying as epsilon squared, and random protocols cause rapid decay.

Su-Schrieffer-Heeger model driven by sequences of two unitaries: periodic, quasiperiodic, aperiodic, and random protocols
Periodic driving of the SSH model with two unitaries produces end modes whose count can mismatch the winding number, while quasiperiodic protocols yield Loschmidt echoes that oscillate near one for long times before decaying as epsilon squared, and random protocols cause rapid decay.
