A Kapitza–Dirac–Talbot–Lau interferometer for highly polarizable molecules [PDF]

Nature Physics, 2007
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clusters and hot molecules. Coherence experiments with complex objects are of interest for exploring the transition to classical physics, for measuring molecular properties and ...

From Surface to Depth: SWOT Altimetry and Glider Observations of a Cuddy in the Northeast Pacific

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract California Undercurrent Eddies (Cuddies) transport heat, salt, and biogeochemical properties from coastal regions to the open Northeast Pacific, but their three‐dimensional structure, lateral exchange mechanisms and complete life‐cycle are still not fully understood.

Tunable X-ray dark-field imaging for sub-resolution feature size quantification in porous media

Scientific Reports, 2021
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

Laser &Photonics Reviews, Volume 20, Issue 10, 22 May 2026.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Transport of Peroxyacyl Nitrates (PANs) Across Northern Hemisphere Ocean Basins From Satellite Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We leverage global satellite observations of Peroxyacyl Nitrates (PANs) from the Cross‐track Infrared Sounder (CrIS) on the Suomi National Polar‐orbiting Partnership satellite to evaluate seasonal and interannual variations of intercontinental transport in the Northern Hemisphere between 2016 and 2022.
