Abstract

Abstract: Nontrivial quantum effects in biological systems are of high interest among physicists over the past decade. They allow for information and energy to be exchanged with near-unity efficiency despite hindered by the warm, wet, and noisy environment. Several models suggests that the efficient quantum energy transport is due to the interplay between dephasing dynamics and unitary evolution of the disordered biological systems i.e in photosynthetic complex. However, the proposed models have not yet included the driving force depicting the external perturbation used in the experiment such as laser in 2D spectroscopy involved in the detection of the exciton transfer or an artificial quantum transport experiments. Here, we resolve this issue by subjecting the dephasing assisted transport model by Plenio and Huelga [ New J. Phys. 10, 11 (2012)] to a driving force. We analyze dynamical evolution of the driven system and show that further efficiency enhancement achieved by driving the transport site. We also discuss some experimental realizations of the quantum transport system.
