Chemical Behavior Under Extreme Conditions

Abstract

Computed ultrafast, (attosecond), electron migration in LiH where the axis of the molecule is along the z direction. The computation demonstrates the control that can be applied via the polarization of the pump laser. Shown is a three dimensional plot of the motion of the electronic dipole of LiH. Shown are the x and z components of the dipole as time unfolds. The pump pulse is short, about 1 fs. (Left). A pump pulse polarized in he z direction. The dipole oscillates along z and there is no component along the x axis. (Right). A pump polarized along the xz direction. The longest period is a rotation of the dipole about the axis of the molecule with a period of about 4 fs. This period is indicated.
