Quantum Energy Expectation in Periodic Time-Dependent Hamiltonians via Green Functions

Quantum Energy Expectation in Periodic Time-Dependent Hamiltonians via Green Functions

Let U F be the Floquet operator of a time periodic Hamiltonian H ( t ). For each positive and discrete observable A (which we call a probe energy ), we derive a formula for the Laplace time average of its expectation value up to time T in terms of …
