Floquet's theorem

WebBloch theorem in solid state theory). In this article we deal with Floquet theory, questions about the completeness of the Floquet solutions, and the connection between the distribution of the multipliers and various properties of the equation. Basically we shall deal with equations that are periodic in several variables (more often—in all). 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 ...
