Three Myths about Time Reversal in Quantum Theory
... supposing time reversal does more than reverse the order of states in a trajectory. The standard expression of time reversal maps a trajectory w(t) to Tw(2t), reversing the order of a trajectory t ↦ 2t but also transforming instantaneous states by the operator T. Both Callender and Albert propose th ...

Therefore, in order to calculate the Floquet state of a system with N > 103 states, the propagation stage has to be included into an algorithm. A propagation method should guarantee a high accuracy with respect not only to the ...
