The long-lived quantum coherence in photosynthesis is a fundamental phenomenon that reflects the quantum nature of microscopic biological systems and may be closely related to the highly efficient excitation energy transfer.Recently,the origin of this phenomenon has been attributed to both electronic and vibrational/vibronic causes.In this work,we further study the non-Condon vibronic coupling effects on the quantum coherence of excitation energy transfer,via the exact dissipaton equation of motion(DEOM)evaluations on excitonic model systems.
