Unifying Collective Effects in Emission, Absorption, and Transfer
Adesh Kushwaha, Erik M. Gauger, Ivan Kassal
Collective effects, such as superradiance and subradiance are central to emerging quantum technologies -- from sensing to energy storage -- and play an important role in light-harv…

Engineering Quantum-Enhanced Transport by Supertransfer
Adesh Kushwaha, Ivan Kassal
Collective behaviour of the components of a quantum system can significantly alter the rates of dynamical processes within the system. A paradigmatic collective effect is superradi…

Light-harvesting efficiency cannot depend on optical coherence in the absence of orientational order
Dominic M Rouse, Adesh Kushwaha, Stefano Tomasi +3
The coherence of light has been proposed as a quantum-mechanical control for enhancing light-harvesting efficiency. In particular, optical coherence can be manipulated by changing…
