Floquet-Majorana Driven Topological Wire

A Floquet-Majorana system is a periodically driven Kitaev chain (1D p-wave superconductor). The Floquet operator U(T) = Te^{−i∫H(t)dt} has quasi-energies in [−π/T, π/T]. Majorana edge modes appear at quasi-energy 0 (regular topological) and π/T (anomalous Floquet phase). The topological invariant W ∈ {0,±1,±2} counts protected edge modes. Phase boundaries: |μ/t| = 2 (static), drive reshapes them.
