Floquet's theorem

WebSo the Floquet manifold is either one big continuum, or multiple overlapping continua, which are equivalent given the usual Floquet-ladder degeneracy. For a discrete spectrum, simply take any finite-dimensional initial Hilbert space H and add any periodic hamiltonian H ( t) = H ( t + T). Then the quasienergies ε (or rather, the exponentiated ...
