Quantum Master Equation Approach to Exciton Recurrence Motion in a Ring-Shaped Aggregate Complex Induced by Circular-Polarized Laser Field

Abstract

The exciton dynamics in a ring‐shaped aggregate complex model induced by circular‐polarized laser field has been investigated using the quantum master equation (QME) approach. We observe the recurrence motion of exiton after the irradiation of a circular‐polarized laser field. It is found that the circular‐polarized laser field makes it possible to shift the oscillation phase of the exciton recurrence and thus to cause the out‐of‐phase recurrence motion, while such unique recurrence dynamics disappears in the case of the irradiation of the linear‐polarized laser field. It also turns out that the direction of phase‐shift in exciton recurrence oscillation can be controlled by the rotation direction of the circular‐polarized laser field.
