Quantum control of I2 wave packet localization in solid argon matrix

Abstract

A hybrid quantum/classical approach for treating the vibrational and translational motion of the I2 molecule inside a cold Ar matrix is implemented in the control of vibrational wave packet localization on the excited (A) electronic surface of I2. Quantum control was performed in the weak-field regime at six different temperatures to examine thermal effects on the dynamics of I2 inside the lattice and on the degree of control that can be achieved for this system. It was found in this study that an increase in temperature from 0 to 75 K leads to a moderate decrease in the degree of control achieved. The role played by I2 rotation on control was also shown to be minimal under the conditions examined in this work.
