Incorporating Particle Settling Enhancement in a Coarse‐Mode Deposition Model

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Dry deposition rates are usually assumed to rely primarily on gravitational settling, with some enhancement due to interactions with surface elements. However, it is known through experiment, theory, and simulation that vertical velocities of particles in turbulent flows can be enhanced by hydrodynamic effects (often referred to as ...

Lagrangian Time Scale of Passive Rotation for Mesoscale Particles in Turbulence

Frontiers in Marine Science, 2020
Turbulence induces rotation in the living and the non-living materials in the ocean. The time scale of rotation for a living organism is important in understanding an organism's feeding efficiency, mating, prey capture rate, etc.

Quantifying the Impact of Temporal and Spatial Heterogeneity in Turbulence on Bed‐Load Transport Over Vegetated Beds Under Wave‐Current Conditions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Laboratory experiments measured velocity and bedload transport in vegetated channels under current‐dominated, combined wave‐current conditions. Waves and vegetation, respectively, introduced temporal and spatial heterogeneity in the velocity, which significantly impacted sediment transport rate.

Propagation Properties of the COAM Matrix of Twisted Gaussian Schell-Model Beams in Non-Kolmogorov Turbulence

Photonics
Based on the extended Huygens–Fresnel principle and mode expansion theory, we derive the expression for the Coherence-Orbital Angular Momentum (COAM) matrix of twisted Gaussian Schell-model (TGSM) beams propagating through non-Kolmogorov turbulence ...

C. F. v. Weizsächer on Quasistationary Isotropic Turbulence Compared With Onsager's Statistical Hydrodynamics

Natural Sciences, Volume 6, Issue 2, April 2026.
v. Weizsäcker and Heisenberg began their turbulence collaboration in 1945 while still quarantined at Farm Hall. Their papers were submitted separately in 1946 from Göttingen. v. Weizsäcker had derived the 5/3 law for dissipation while using dimensional analysis in real space.

XY model for cascade transfer

Physical Review Research, 2022
We propose a modified XY model in which cascade transfer emerges from spatially local interactions where the spin corresponds to the “velocity” of a turbulent field.

String Theory and Turbulence [PDF]

, 2010
We propose a string theory of turbulence that explains the Kolmogorov scaling in 3+1 dimensions and the Kraichnan and Kolmogorov scalings in 2+1 dimensions. This string theory of turbulence should be understood in light of the AdS/CFT dictionary.

A Model Intercomparison Study to Investigate Mixing Characteristics in Non‐Precipitating Stratocumulus Clouds

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Recent aircraft observations of marine stratocumulus clouds consistently showed that cloud microphysical relationships vary with altitude, indicating inhomogeneous mixing characteristics near cloud top and homogeneous mixing characteristics in mid‐levels of clouds.

Quantum algorithm for Bose-Einstein condensate quantum fluid dynamics

, 2009
The dynamics of vortex solitons in a BEC superfluid is studied. A quantum lattice-gas algorithm (localization-based quantum computation) is employed to examine the dynamical behavior of vortex soliton solutions of the Gross-Pitaevskii equation (phi^4 ...
