The subatomic world is a realm where matter behaves in ways that defy our everyday intuition, and this category explores the fundamental building blocks of our universe. From the intricate dance of quarks inside a proton to the strange properties of electrons, these studies reveal the deep rules that govern everything from the smallest particles to the largest stars.

At Gist.Science, we track every new preprint in this field as it appears on arXiv, ensuring you stay ahead of the curve. For each discovery, we provide both a clear, plain-language explanation of the core ideas and a detailed technical summary for those who want to dive deeper into the mathematics and methodology.

Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.

Tracking electron capture processes in classical molecular dynamics simulations for spectral line broadening in plasmas

This paper introduces a new classical molecular dynamics algorithm that precisely identifies electron capture events and stable orbits for ions with charges Z ≥ 1, thereby enabling accurate tracking of electric microfield time-histories for spectral line broadening calculations and validating its results against potential energy and atomic kinetic simulation methods.

Demonstration of deuterium's enhanced sensitivity to symmetry violations governed by the Standard-Model Extension

This paper reports hyperfine spectroscopy of ground-state deuterium that sets the first constraints on spin-independent Standard-Model Extension coefficients with momentum powers k=2 and 4, while improving bounds on spin-dependent coefficients by 4 to 14 orders of magnitude over previous hydrogen maser measurements through enhanced sensitivity to CPT and Lorentz symmetry violations.

Modeling Compressive Instability in Two-Dimensional Ti2COx MXenes

This study utilizes molecular dynamics simulations and a nonlocal continuum formulation to characterize the compressive instability and post-buckling behavior of Ti2COx MXenes, revealing that classical mechanics underestimates buckling strains while factors like defect clustering, surface termination, and confinement significantly influence critical stress and deformation modes.

Transformation of vector modes by the Faraday effect in strong magnetic fields

This paper investigates how strong magnetic fields in a rubidium vapour induce Faraday rotation and dichroism in the Hyperfine Paschen-Back regime, demonstrating that azimuthally polarized light transforms into radial polarization at low densities while exhibiting complex alignment and ellipticity variations at high densities.

One more radiative-recoil correction to the Lamb shift in muonium

This paper calculates a specific radiative-recoil correction of order $Z^2\alpha(Z\alpha)^5(m/M)^2m$ to the Lamb shift in muonium, arising from radiative photon insertions in the heavy line of two-photon exchange diagrams, to support ongoing high-precision $1S-2S$ and $2S-2P$ experiments.
