Atmospheric clustering explores how tiny particles in the air group together to form clouds, fog, and even influence our weather patterns. This fascinating intersection of physics and meteorology reveals the invisible dance of molecules that shapes everything from a gentle breeze to a massive storm system. Understanding these microscopic interactions is key to predicting climate change and improving air quality forecasts for communities worldwide.
On Gist.Science, we track every new preprint published in the atmospheric clustering category on arXiv.

This paper establishes that shape resonances in photoionization provide a fundamental link between the photoionization cross section and the Wigner time delay, enabling the extraction of time delays from existing cross-section data to validate modern interferometric measurements.
This paper reports the total integrated and triple differential cross-sections for two-photon double ionization of helium in the 42–50 eV photon energy range, revealing a monotonic growth in cross-section and exploring the previously uninvestigated 47–50 eV region through numerical solutions of the time-dependent Schrödinger equation.
This paper demonstrates that chiral molecules support time-even spin-momentum correlations in photoionization that are revealed only through conditioned measurements, arguing that such correlations constitute the fundamental origin of chirality-induced spin selectivity (CISS) phenomena and identifying the specific molecular pseudovectors governing these spin-conditioned photoelectron currents.
Using the lowest-order constrained variational approach, this study determines the minimal boson-boson repulsion required to ensure mechanical stability in two-dimensional Bose-Fermi mixtures with tunable interactions, revealing that equal mass ratios significantly enhance stability and require the least repulsion to prevent collapse.
This paper presents a highly precise and efficient experimental method for determining the ionization energies and work functions of temperature-controlled alkali metal nanoparticles in a beam by combining a stable condensation source, thermalization, tunable photoionization, and automated data analysis using the universal Fowler function.
This study demonstrates that high-resolution photoionization threshold measurements of 7–9 nm sodium and potassium nanoparticles can detect thermal expansion and a distinct melting transition, revealing a melting point suppression of nearly 100 K that aligns with Gibbs-Thomson predictions.
By measuring the work functions of 6Li and 7Li nanoparticles via photoionization, researchers discovered a significant isotope effect and anomalous temperature dependence that highlight lithium's complex quantum nature and confirm the Third Law of thermodynamics prediction that the work function slope vanishes at low temperatures.
This study utilizes a time-dependent model of Jupiter's circumplanetary disk to demonstrate that thermal processing of ices is the dominant pathway for forming complex organic molecules, suggesting that the Galilean moons likely inherited these prebiotic compounds through cold, prolonged accretion processes.
This study reports the on-surface synthesis and atomic-scale characterization of antiferromagnetic S=1/2 quantum spin rings composed of [2]triangulene units on Au(111), revealing that while planar six-membered rings exhibit uniform excitation gaps describable by a Heisenberg model, distorted five-membered rings display asymmetric spin ground states due to structural distortion-induced degeneracy lifting.
This paper presents a numerical simulator for optical pumping and develops experimental methodologies to precisely characterize the 36 optical-hyperfine transitions in under a magnetic field, ultimately deriving the optical dipole moment for the transition.
