Control of mixed-state quantum systems by a train of short pulses
D. Sugny, A. Keller, O. Atabek +4
A density matrix approach is developped for the control of a mixed-state quantum system using a time-dependent external field such as a train of pulses. This leads to the definitio…
Laser control for the optimal evolution of pure quantum states
D. Sugny, A. Keller, O. Atabek +4
Starting from an initial pure quantum state, we present a strategy for reaching a target state corresponding to the extremum (maximum or minimum) of a given observable. We show tha…
Field-free two-direction alignment alternation of linear molecules by elliptic laser pulses
D. Daems, S. Guérin, E. Hertz +3
We show that a linear molecule subjected to a short specific elliptically polarized laser field yields postpulse revivals exhibiting alignment alternatively located along the ortho…
Efficient and long-lived field-free orientation of molecules by a single hybrid short pulse
D. Daems, S. Guérin, D. Sugny +1
We show that a combination of a half-cycle pulse and a short nonresonant laser pulse produces a strongly enhanced postpulse orientation. Robust transients that display both efficie…
