Quantum interference overcomes photoexcitation annihilation
August 4, 2023
Quantum phase relationships of photoexcitations impact the behavior of excitons—photoexcitations don’t always annihilate each other when quantum phases interfere destructively—and it can be tapped to influence molecular material design.
A team of researchers from Northwestern University (Roel Tempelaar) and Purdue University (Libai Huang) experimentally demonstrated control of annihilation by quantum interference—proving photoexcitation is even more intriguingly complex than we imagined.
