Description: Nature realizes a vast array of complex structures composed of molecular building blocks, the electronic structure of which can be well described by quantum mechanics. In photosynthetic light harvesting, for example, quantum behavior within complex nanoscale structures has generated tremendous recent interest. While there is remarkable potential that photosynthetic systems are, in a sense, behaving as quantum devices, the exact relationship between structure and the properties of quantum states (e.g., coherence) remains a topic of vigorous debate. In this talk, I describe a new paradigm – based on internal thermodynamic fluctuations in a QHE photocell – that attempts to describe highly efficient light energy harvesting in complex quantum structures. By understanding the connection between electronic structure and energy fluctuations, I describe an intrinsic regulation mechanism that emerges from quantum structure alone. Beyond gaining a deeper understanding of quantum optoelectronics, the natural regulation process described here promises to have applications across various disciplines ranging from quantum nanoscience and computing to bionanoscience and astrobiology. Natural regulation may also explain the predominance of green plants on Earth.
