Single-photon absorption and emission from a natural photosynthetic complex. [PDF]

Nature, 2023
AbstractPhotosynthesis is generally assumed to be initiated by a single photon1–3 from the Sun, which, as a weak light source, delivers at most a few tens of photons per nanometre squared per second within a chlorophyll absorption band1. Yet much experimental and theoretical work over the past 40 years has explored the events during photosynthesis ...

Emulation of coherent absorption of Fock-state quantum light in a programmable linear photonic circuit. [PDF]

Nat Commun
Non-Hermitian quantum systems, governed by nonunitary evolution, offer powerful tools for manipulating quantum states through engineered loss. A prime example is coherent absorption, where quantum states undergo phase-dependent partial or complete ...

Quantifying Annual Photon Absorption in 55 Bamboo Species: A Standardized Modeling Approach Using Peak-Season Leaf Optical Traits and Long-Term Radiation Data. [PDF]

Plants (Basel)
To accurately quantify the intrinsic absorption efficiency of bamboo leaves to the solar spectrum, we measured the reflectance and transmittance of leaves from 55 bamboo species cultivated at the same site, and developed a mathematical model to calculate
