Photosynthetic light‐use efficiency of rice leaves under fluctuating incident light
Agrosystems, Geosciences & Environment, 2020 The responsiveness of photosynthesis to continuously fluctuating light intensities can provide an estimate of the net assimilation rate (A) and photosynthetic light‐use efficiency (PLUE), which cannot be measured under steady‐state conditions. This study

Palisade cell shape affects the light-induced chloroplast movements and leaf photosynthesis [PDF]
, 2018 Leaf photosynthesis is regulated by multiple factors that help the plant to adapt to fluctuating light conditions. Leaves of sun-light-grown plants are thicker and contain more columnar palisade cells than those of shade-grown plants.

Role of Equilibrium Fluctuations in Light-Induced Order
Physical Review Letters, 2021 Engineering novel states of matter with light is at the forefront of materials research. An intensely studied direction is to realize broken-symmetry phases that are "hidden" under equilibrium conditions but can be unleashed by an ultrashort laser pulse. Despite a plethora of experimental discoveries, the nature of these orders and how they transiently

Quantum theory of dynamic multiple light scattering
, 2007 We formulate a quantum theory of dynamic multiple light scattering in fluctuating disordered media and calculate the fluctuation and the autocorrelation function of photon number operator for light transmitted through a disordered slab.

Experimental Demonstration of Squeezed State Quantum Averaging [PDF]
, 2010 We propose and experimentally demonstrate a universal quantum averaging process implementing the harmonic mean of quadrature variances. The harmonic mean protocol can be used to efficiently stabilize a set of fragile squeezed light sources with ...

A fluctuating environment as a source of periodic modulation
, 2007 We study the intermittent fluorescence of a single molecule, jumping from the "light on" to the "light off" state, as a Poisson process modulated by a fluctuating environment.

The Uncertainty Principle derived by the finite transmission of light and information [PDF]
, 2013 This work shows that in the frame of the stochastic generalization of the quantum hydrodynamic analogy (QHA) the uncertainty principle can be derived by the postulate of finite transmission speed of light and information .

Photosynthetic Acclimation to Fluctuating Irradiance in Plants
Frontiers in Plant Science, 2020 Unlike the short-term responses of photosynthesis to fluctuating irradiance, the long-term response (i.e., acclimation) at the chloroplast, leaf, and plant level has received less attention so far.

Magnification Ratio of the Fluctuating Light in Gravitational Lens 0957+561
, 1998 Radio observations establish the B/A magnification ratio of gravitational lens 0957+561 at about 0.75. Yet, for more than 15 years, the optical magnfication ratio has been between 0.9 and 1.12.

Far-Red Light Accelerates Photosynthesis in the Low-Light Phases of Fluctuating Light [PDF]
Plant and Cell Physiology, 2019 Abstract It is well known that far-red light (FR; >700 nm) drives PSI photochemistry, but its effect on photosynthetic performance has received little attention. In this study, the effects of the addition of FR to red fluctuating light (FL) have on photosynthesis were examined in the leaves of Arabidopsis thaliana.
