Quantum Energy Expectation in Periodic Time-Dependent hamiltonians via Green Functions
Cesar R. de Oliveira, Mariza S. Simsen
Let be the Floquet operator of a time periodic hamiltonian . For each positive and discrete observable (which we call a {\em probe energy}), we derive a formula for…

Almost Periodic Orbits and Stability for Quantum Time-Dependent Hamiltonians
Cesar R. de Oliveira, Mariza S. Simsen
We study almost periodic orbits of quantum systems and prove that for periodic time-dependent Hamiltonians an orbit is almost periodic if, and only if, it is precompact. In the cas…
