Environmentally Improved Coherent Light Harvesting

Coherence-enhanced light harvesting has not been directly observed experimentally, despite theoretical evidence that coherence can significantly enhance light-harvesting performance. The main experimental obstacle the difficulty in isolating effect of presence confounding variables. Recent proposals for externally controlling by manipulating light's degree polarization showed coherent efficiency enhancements would be possible, but were restricted to systems weakly coupled their environment. Here, we show increases system-bath coupling strength amplify enhancements, rather than suppress them. This result dramatically broadens range could used conclusively demonstrate coherence-enhanced or engineer effects into artificial devices.
