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.

Effects of intertube dipole-dipole interactions in nearly integrable one-dimensional 162^{162}Dy gases

This study demonstrates that while intertube dipole-dipole interactions in nearly integrable one-dimensional 162^{162}Dy gases slightly alter both equilibrium properties and rapidity measurements, these opposing effects nearly cancel each other out, resulting in measured rapidity distributions that closely match predictions made without considering such interactions.

Ab Initio Calculations of the Static and Dynamic Polarizability of BaOH

This paper presents high-precision relativistic coupled-cluster calculations of the static and dynamic polarizabilities for the ground and (010) vibrational states of BaOH, establishing a rigorous uncertainty quantification procedure and validating the results through comparison with experimental dipole moment data.

Four- and six-photon stimulated Raman transitions for coherent qubit and qudit operations

This paper experimentally demonstrates high-fidelity coherent control of single-atom qubits and qudits by achieving four- and six-photon stimulated Raman transitions with magnetic quantum number changes of ΔmJ=3,4,\Delta m_J = 3, 4, and $5$, while providing a theoretical framework and pathways to reach fidelities exceeding 99.99%.

Optimized Phase Masks for Absorption of Ultra-Broadband Pulses by Narrowband Atomic Ensembles

This paper theoretically demonstrates that combining genetic algorithms with spatial light modulators can significantly enhance two-photon cascade absorption in narrowband atomic ensembles, achieving up to a 26-fold improvement for sequential transitions driven by separate pulses, though practical gains for weak probe storage under specific experimental conditions remain modest.

High-resolution spectroscopy of 162Dy Rydberg levels

This paper reports the first high-resolution spectroscopy of over 700 Rydberg states in 162Dy, achieving a tenfold improvement in the precision of its ionization potential and utilizing multichannel quantum defect theory to characterize perturbing states, thereby establishing a foundation for dysprosium-based quantum architectures and benchmarks for ab-initio calculations.

Atomic parity violation in highly charged 40,48^{40,48}Ca and 208^{208}Pb ions

This paper calculates parity-violation-induced E1 amplitudes for specific transitions in H- and Li-like calcium and lead ions, concluding that while neutron-skin corrections can be neglected for calcium isotope comparisons in searches for new ZZ' boson physics, both neutron-skin effects and sensitivity to such interactions are significant for 208^{208}Pb.

Encoding electronic ground-state information with variational even-tempered basis sets

This paper proposes a system-oriented, symmetry-adapted even-tempered basis set design that uses primitive S-subshell Gaussian-type orbitals and only two parameters to efficiently and accurately encode electronic ground-state information, achieving high-quality results for hydrogen systems with reduced optimization costs and improved scalability.
