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.

Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
The authors developed a surface-electrode ion trap featuring a silicon-etched hole for collimated atomic loading, which enables efficient, isotope-selective sympathetic cooling and the direct generation of ion chains suitable for quantum architectures and precision measurements.
This paper extends the Harrow-Hassidim-Lloyd (HHL) algorithm to qutrits by introducing Weyl-Heisenberg gadgets and a practical implementation scheme, demonstrating that the qutrit version achieves comparable precision with fewer qudits and a similar number of two-qudit gates compared to the traditional qubit-based approach.
This paper proposes a purely optical macroscopic trap for alkaline-earth atoms using a bichromatic field resonant with closed optical transitions, which generates new kinetic effects to achieve sub-Doppler cooling and serves as a magnetic-field-free alternative to magneto-optical traps for advanced quantum sensors and frequency standards.
This paper presents an experimental study at the HIRFL-CSR storage ring demonstrating that the angular distribution of Kα1 radiation from Xe52+ ions produced via nonradiative double electron capture in collisions with Kr and Xe targets is anisotropic and sensitive to collision energy and target type, while Kα2 radiation remains isotropic, revealing distinct differences from single electron capture processes.
This paper presents an extended theoretical framework for atomic-scale Stark-shift spectroscopy using light-assisted scanning tunneling microscopy to map subnanometric charge redistribution and polarizability changes in organic molecules under realistic, inhomogeneous electric fields.
This paper reports the experimental preparation and measurement of long-lived metastable states in the 4f5d6s configuration of a single trapped Yb ion, revealing lifetimes ranging from 0.92 s to over 30 s that are corroborated by atomic structure calculations and offer new prospects for quantum information and optical clock applications.
The paper proposes a novel nuclear interferometer utilizing the thorium-229 clock transition to detect ultra-light dark matter, offering enhanced sensitivity to variations in fundamental constants and the QCD sector that could complement and surpass existing terrestrial clock experiments.
This paper establishes a comprehensive Fisher information-based framework for Rydberg atom microwave electrometry that derives an analytical sensitivity expression combining photon shot noise and atomic response, demonstrating that cesium vapor systems can achieve robust sub-nanovolt sensitivity under optimal conditions.
This paper presents a consensus-based algorithm that optimizes qubit positions on neutral atom platforms to tailor interatomic interactions, thereby accelerating convergence and mitigating barren plateaus in variational quantum algorithms for ground state minimization problems.
This paper demonstrates through large-scale simulations and analytical estimates that superradiance in disordered waveguide quantum electrodynamics remains robust against strong spatial and spectral disorder, driven by a spontaneous self-organization of spins that optimizes constructive interference and leads to mirror-asymmetric correlations.
