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.

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.
This paper introduces an adaptive, symmetry-informed Bayesian metrology strategy that significantly enhances parameter estimation precision in quantum technology experiments, achieving a five-fold reduction in variance or a three-fold reduction in required data compared to standard methods.
This paper introduces Reinforcement-Learning-Designed Quantum Logic Spectroscopy (RL-QLS), a novel framework that utilizes reinforcement learning to optimize pulse sequences for preparing polyatomic molecular ions, such as HO and CaH, into pure quantum states, thereby enabling high-precision tests of fundamental physics despite complex internal structures and environmental disturbances.
This paper proposes a highly efficient and directional single-photon transduction scheme using cooperative Rydberg metasurfaces and 4-wave mixing to convert terahertz signals into optical photons, achieving up to 50% efficiency in specific directions for applications in quantum sensing and networking.
This paper reports the first experimental demonstration of storing and retrieving optical skyrmions in a cold Rb vapor using dual-path electromagnetically induced transparency, confirming that their topological skyrmion number remains robust against perturbations and imbalanced loss for several microseconds.
This paper demonstrates that bright squeezed vacuum light selectively enhances holographic structures in xenon photoelectron momentum distributions by leveraging intrinsic trajectory coherence to filter out dephasing noise, thereby establishing a new regime of quantum-enabled, noise-resilient strong-field ionization.
This paper presents a complete theoretical calculation of the muonic hydrogen (H) ground-state hyperfine splitting, incorporating direct quantum electrodynamic and recoil corrections alongside proton structure effects derived from hydrogen data, to yield a prediction of eV with precision exceeding 1 ppm.
This paper reports a 4-K cryogenic platform that utilizes high numerical aperture optics and dual-wavelength trapping to achieve 5000-second lifetimes and prepare defect-free arrays of up to 1024 atoms, significantly advancing prospects for large-scale quantum computing.
This paper investigates ultraviolet ground state transitions in dysprosium using two-dimensional shelving spectroscopy to characterize their hyperfine-isotope structure and decay strengths, thereby enabling applications in optical clocks, quantum gas microscopy, and searches for physics beyond the standard model.
This paper introduces a symmetrization scheme that preserves the Mermin-Wagner theorem to resolve pseudo phase transitions in the 2D Hubbard model, applying it within a GW-covariance framework to accurately calculate Green's and spin-spin correlation functions that align with DQMC benchmarks while satisfying fundamental many-body relations.
This paper reports new high-precision Fourier-transform microwave spectroscopic measurements and a global isotopic analysis of five BaF isotopologues, which significantly improve hyperfine parameters and reveal distinctive Born-Oppenheimer breakdown structures driven by nuclear field shifts, thereby supporting future searches for physics beyond the Standard Model such as the electron electric dipole moment.
