4.One clarification regarding this computation is necessary. In accord with the idea of phase control, the authors' intention is to vary without changing . They proposed to do so by varying the chirp parameter in the laser field [their Eq. (8)]. However, computing from their shows that it depends upon . Hence, dynamical effects in their Fig. 4 that result from changing the sign of are indeed evidence for phase control. However, dynamical effects resulting from varying are a result of changes to both the relative phases and to , and are hence not evidence of phase control. Alternate computations showing phase control have been obtained as well (R. Kosloff, private communication).

13.Interestingly, in model systems studied with a Redfield approach we found that we could generally construct different wavepackets “by hand” on an excited potential energy surface that displayed the desired phase dependent control behavior. However, these wavepackets could not be obtained via one-photon excitation from the ground state.

Abstract

Coherent control of observables using the phase properties of weak light that induces one-photon transitions is considered. Measurable properties are shown to be categorizable as either class A, where control is not possible, or class B, where control is possible. Using formal arguments, we show that phase control in open systems can be environmentally assisted.
