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.

Effect of dipole interactions on the properties of an expanding ultracold plasma: A study using quantum mechanical scattering theory

This paper extends a previously developed quantum mechanical scattering theory to various atomic species, demonstrating that interactions between remaining neutral atoms and electrons in expanding ultracold plasmas induce Rydberg ionization, three-body recombination, and a "quantum pressure" that explains previously anomalous experimental observations of faster plasma expansion.

Hydrogen photoionization in a magnetized medium: the rigid-wavefunction approach revisited

This paper presents a comprehensive revision of the rigid-wavefunction approach for calculating hydrogen photoionization in magnetized media, providing explicit expressions for transition probabilities and occupation numbers that reveal significant modifications to absorption opacities and pronounced dichroic features even at magnetic field strengths below 10 MG.

Semiclassical description of Interatomic Coulombic Electron Capture in solutions

This paper presents a semiclassical molecular dynamics simulation using OpenMM to demonstrate that the quantum yield of Interatomic Coulombic Electron Capture (ICEC) in aqueous solutions containing Fe $^{3+}$ cations approaches unity at higher concentrations and electron energies, while decreasing at lower concentrations due to energy loss.

Electromagnetically induced transparency and population repump readout of Rydberg states of Cs atoms in a J-scheme

This paper demonstrates a miniaturizable three-photon Rydberg electrometry scheme for Cesium atoms using a J-level coupling and external cavity diode lasers, achieving competitive electric field sensitivity of 27 μV m⁻¹ Hz⁻¹/² at 4.7 GHz without requiring tapered amplifiers or frequency doubling crystals, while also exploring a modified population repump readout configuration.

Multimessenger Astronomy Beyond the Standard Model: New Window from Quantum Sensors

This paper proposes that quantum sensors can detect bursts of ultralight bosonic fields emitted during violent astrophysical events, thereby establishing a new multimessenger astronomy channel that remains viable even when accounting for matter screening effects.

Laser Excitation of Muonic 1S Hydrogen Hyperfine Transition: Effects of Multi-pass Cell Interference

This paper develops a model to estimate the upper bound of interference effects in multi-pass cells on laser-induced muonic hydrogen hyperfine transitions, concluding that while neglecting these effects can theoretically overestimate transition probabilities, they are negligible under the specific experimental conditions studied.

An Atomic Interface for High-Dimensional Temporal Mode Quantum Networks

This paper demonstrates a programmable high-dimensional temporal mode processor using a Raman quantum memory in warm cesium vapor, which enables on-demand storage, filtering, and conversion of orthogonal temporal waveforms to serve as a coherent interface between MHz- and GHz-bandwidth modes for scalable quantum networks.

Driven-Dissipative Landau Polaritons: Two Highly Nonlinearly-Coupled Quantum Harmonic Oscillators

This paper demonstrates that a driven-dissipative system coupling the Landau levels of a charge-neutral particle in a synthetic gauge potential to a quantized optical cavity can be effectively modeled as two highly nonlinearly coupled quantum harmonic oscillators, giving rise to hybrid "Landau polaritons" with unique entanglement, squeezing, and diverse nonequilibrium dynamics.

Unambiguous Vector Magnetometry with Structured Light in Atomic Vapor

This paper proposes a method to resolve the ambiguity in vector magnetometry caused by anti-parallel magnetic fields by utilizing structured light and Fourier analysis of absorption profiles in optically polarized atomic vapor to achieve unambiguous, complete characterization of arbitrarily oriented magnetic fields.
