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.

Capture velocities for direct loading of heavy molecules into conveyor-belt magneto-optical traps

This paper demonstrates through theoretical calculations that the conveyor-belt magneto-optical trap (CB-MOT) mechanism, which enables efficient direct loading of heavy molecules like BaF, remains effective for other isotopes and species with complex hyperfine structures or limited radiative forces, thereby offering a robust alternative to conventional MOTs for a broader range of laser-coolable molecules.

An \Al clock with 1.6×10−181.6\times10^{-18} systematic uncertainty and its frequency ratios

This paper reports the full systematic evaluation of an Al+^+ single-ion optical clock achieving a fractional frequency uncertainty of 1.6×10−181.6\times10^{-18}, alongside precise measurements of its absolute frequency and its ratio to a Sr optical lattice clock, which show a significant deviation from previous BACON collaboration results and support the ongoing redefinition of the second.

A dipolar Bose-Bose mixture of Dysprosium isotopes with controllable interspecies interactions

This paper reports the realization of a quantum-degenerate Bose-Bose mixture of dysprosium isotopes (162Dy and 164Dy) with efficient thermalization and tunable interspecies interactions via a Feshbach resonance, enabling the exploration of a miscible-immiscible transition and dipolar effects such as multi-component supersolidity.

Structure and information measures of few-electron systems under a spherically symmetric Gaussian potential within a density functional approach

This study employs a density functional approach with the generalized pseudospectral method to investigate the energies and information-theoretic measures of few-electron systems under a spherically symmetric Gaussian potential, revealing how variations in potential width and depth influence electron correlation, density localization, and the behavior of specific exchange-correlation functionals.

Scattering and sputtering on the lunar surface; Insights from negative ions observed at the surface

Using data from the Chang'e-6 lander's NILS instrument, this study employs a novel semi-analytical model to quantify the scattering and sputtering of solar wind protons on the lunar surface, revealing specific probabilities for negative ion emission, the influence of surface roughness on angular distributions, and a surface binding energy of 5.5 eV.

Tripartite entanglement of remote atomic qubits

This paper reports the first generation of a fully distributed Greenberger-Horne-Zeilinger (GHZ) state across a three-node quantum network of single atomic memories using photonic interconnects, achieving high fidelity and a clear violation of Mermin's inequality while closing the detection loophole.

Creating squeezed and non-classical collective motional many-body states through stroboscopic Rydberg dressing

This paper proposes a method for neutral atom quantum computing platforms that utilizes stroboscopic Rydberg dressing to collectively squeeze interatomic distance fluctuations and generate non-classical motional states, thereby reducing gate infidelities and motional decoherence.
