Computing Floquet Hamiltonians with symmetries

Unitary matrices arise in many ways in physics, in particular as a time evolution operator. For a periodically driven system, one frequently wishes to compute a Floquet Hamiltonian that should be a Hermitian operator H such that e−iTH = U(T), where U(T) is the time evolution operator at time corresp...
