Summary
We studied resonance width distributions in light scattering. Our findings confirm a universal power law, signaling Anderson localization of light in open systems.
Area of Science:
- Physics
- Optics
- Condensed Matter Physics
Background:
- Multiple light scattering is crucial in various optical phenomena.
- Anderson localization describes the absence of diffusion in disordered systems.
Purpose of the Study:
- To investigate the distribution of resonance widths P(Gamma) in multiple light scattering.
- To identify signatures of Anderson localization in open systems.
Main Methods:
- Numerical calculations were performed for one-, two-, and three-dimensional systems.
- Analysis focused on the probability distribution of resonance widths.
Main Results:
- The resonance width distribution P(Gamma) follows a universal power law, P(Gamma) ~ Gamma(-1).
- This power law was consistently observed across different dimensions.
Conclusions:
- The observed power law is a definitive indicator of exponential Anderson localization of light.
- This provides a new method for detecting light localization in open scattering systems.

01:19Protein Dynamics in Living Cells
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

01:37Super-resolution Fluorescence Microscopy
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.
