ProgrammeI.6  Invited, VCTP45 Date: Tuesday, 13 October 2020 Time: 14:30  15:00 Theoretical study of dynamic Starkinduced pielectron rotations in low symmetry aromatic ring molecules beyond the frozen nuclear approximationHirobumi Mineo Ton Duc Thang University, AIMaS Effects of vibrational modes on dynamic Starkinduced pielectron rotations in lowsymmetry aromatic ring molecules were theoretically studied under the adiabatic approximation. The lowest vibronic states in the two electronic excited states are set to be degenerate by using two UV lasers. The parameters of the two lasers (frequencies, intensities) were determined under the condition in which the lowest two vibronic states are in equal energy with each other. The resultant degenerate state is called dynamic Starkinduced degenerate vibronic state (DSIDVS), which is an essential key to generate coherent pielectron angular momentum of aromatic ring molecules taking into account vibrational degrees of freedom. Closed forms of vibronic state wavefunctions are derived by solving the timedependent Schrödinger equations analytically. Here the number of the vibronic excited states were restricted to extract the essential role of vibrational mode on pielectron rotations. In this work we adopt toluene molecule, which is one of the typical aromatic ring molecules with lower symmetry. Presenter: Hirobumi Mineo
