报告简介：
We discuss a variety of recent ultra-fast applications analysed using Next Generation Quantum Theory of Atoms in Molecules (NG-QTAIM) for both molecules and the solid state. This is undertaken using pairs of left- and right-linearily or circularly or elliptically polarized laser pulses on femtosecond or faster time-scales. The carrier-envelope phase (CEP) angle ϕ is varied to learn more about learn more about the relationship ρ(r)→ y(r).
Figure 1: Left. The ethane C1-C2 BCP Hessian of ρ(r) eigenvector-following trajectories TF(s) for the right-handed, clockwise (CW[+1]) and left-handed, counter-clockwise (CCW[-1]) circularly polarized laser pulses of duration 10 femtoseconds for the carrier-envelope phase (CEP) angle ϕ = 0.0° corresponding to the electric field E = 200.0 x 10-4 a.u., see the main text for further explanation. The start and end of each TF(s) are denoted by balls and cubes respectively and are surrounded by an ellipse.
Inset. The corresponding variation of the ethane C1-C2 BCP ellipticity ε, notice the position of the green arrow on the x-axis.
Right. The corresponding ethane C1-C2 BCP TF(s) for the CEP angle ϕ = 180.0°. Notice the changed position of the black ellipse relative to the left figure. Inset. The corresponding variation of the ethane C1-C2 BCP ellipticity ε, notice that the green arrow on the x-axis has moved leftwards relative to that of the left inset.
