    • Note that, as an alternative to FSSH dynamics, the MMST formalism solves this problem correctly without applying collapsing events to force decoher ence. In this case, coherent trajectories interfere by phase cancellation, and one finds the correct branching ratios (Refs. 66-68)

    • note
    • Note, however, that the expressions for decoherence in this paper and in Ref. 52 are not completely analogous. In particular, the equations of motion in Ref. 52 are only approximate, for they were based on Ehrenfest dynamics rather than the quantum Liouville equation. In this paper, we have the correct equations of motion, and we have shown the approximations necessary to rigorously derive Eq. (55).
