Quantum entanglement in photosynthetic light-harvesting complexes
Light-harvesting components of photosynthetic organisms are complex, coupled, many-body
quantum systems, in which electronic coherence has recently been shown to survive for
relatively long timescales, despite the decohering effects of their environments. Here, we …

Unified treatment of quantum coherent and incoherent hopping dynamics in electronic energy transfer: Reduced hierarchy equation approach
A Ishizaki, GR Fleming - The Journal of chemical physics, 2009 - aip.scitation.org
A new quantum dynamic equation for excitation energy transfer is developed which can
describe quantum coherent wavelike motion and incoherent hopping in a unified manner.
The developed equation reduces to the conventional Redfield theory and Förster theory in …

Two-dimensional electronic spectroscopy and photosynthesis: fundamentals and applications to photosynthetic light-harvesting
GS Schlau-Cohen, A Ishizaki, GR Fleming - Chemical Physics, 2011 - Elsevier
In natural light harvesting systems, pigment-protein complexes are able to harvest sunlight
with near unity quantum efficiency. These complexes exhibit emergent properties that
cannot be simply extrapolated from knowledge of their component parts. In this perspective …

Using coherence to enhance function in chemical and biophysical systems
Coherence phenomena arise from interference, or the addition, of wave-like amplitudes with
fixed phase differences. Although coherence has been shown to yield transformative ways
for improving function, advances have been confined to pristine matter and coherence was …
