In particular, the right most portion of the nuclear density is associated with the lower electronic states, whereas the left portion is what has been "transferred" to the upper state at the avoided crossing. For this simple model, TDQT is in extremely good agreement with the benchmark calculations, even though the TDPES is known only numerically on a spatial grid. For instance, evaluating the integrated density beyond x = 12 a 0 at t = 120 fs, one gets a transmitted probability value of 0.84625 using TDQT, which is very close to the exact value of 0.84518 (TDCT yields 0.88584). The dual avoided crossing model, with initial wavepacket launched towards the avoided crossings with initial momentum of k 0 = 10 a -1 0 , presents very quantum-mechanical behavior.
