Observations of wavelike energy transport in photosynthetic systems have exposed the role of quantum mechanics in natural light harvesting. This project is a study of how light harvesting functions for an incoherent source like sunlight. In sunlight, energy transport occurs at steady state, a dramatically simpler regime than when a coherent source like lasers are used. This project will exploit this simplification to develop new methods for treating light harvesting in sunlight and apply them to a variety of natural and artificial systems. It will clarify how bacteria and plants harvest sunlight and lead to design principles that will enable artificial light harvesting to take advantage of quantum effects.

对光合作用系统中波状能量传输的观察揭示了量子力学在自然光收集中的作用。这个项目是研究光收集对于像阳光这样的非相干源是如何起作用的。在太阳光中，能量传输是在稳定状态下进行的，这比使用激光之类的相干光源时要简单得多。这个项目将利用这种简化来开发新的方法来处理阳光下的光收集，并将它们应用于各种自然和人工系统。它将阐明细菌和植物是如何收集阳光的，并得出使人造光收集能够利用量子效应的设计原则。
