Eigenvectors Floquet Hamiltonian

The eigenvectors of K are the same ones as those for K, and the eigenvalues just have to be multiplied by Ha. The difference with the preceding discussion is that here Ho and V are both of order e. Thus we take as the unperturbed Floquet Hamiltonian just... 

The Structure of Eigenvectors and Eigenvalues of Floquet Hamiltonians—The Concept of Dressed Hamiltonian... 

This structure of the eigenvectors and eigenvalues of Floquet Hamiltonians can be understood by considering an alternative interpretation of the Floquet eigenvalue problem.
