Physics & Astronomy Colloquium at CSU Long Beach



Why Are Terrestrial Plants Green?

And Other Essential Questions About Emerging Quantum

Optoelectronic Technologies




Nathaniel Gabor

University of California Riverside

April 24, 2017
Time: 11:15am
Refreshments at 10:45am

While there is remarkable potential that photosynthetic systems harness quantum mechanical effects, the exact relationship between structure and the properties of quantum states remains a topic of vigorous debate. Recently, the concept of a quantum heat engine (QHE) has emerged as an important tool in understanding subtle relationships between form and function in nanoscale quantum systems. In this talk, I describe a new paradigm – based on internal energy 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 a natural regulation mechanism that emerges from quantum structure alone. Beyond gaining a deeper understanding of quantum optoelectronics, the natural regulation process promises to have applications across various disciplines ranging from quantum nanoscience to bionanoscience and astrobiology. Natural regulation may also explain the predominance of green plants on Earth.














All Physics students & faculty should attend!
