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.
This paper demonstrates that geometrically ordered, spatially extended 2D atom arrays with subwavelength spacing enable a new regime of collective light-matter interaction where photon-mediated interactions drive extensive superradiance and subradiance, revealing their underlying magnetic-like correlations and establishing a programmable platform for dissipative many-body quantum physics.
This paper presents a highly scalable, industrially microfabricated 3D ion trap fabricated on stacked 8-inch wafers that achieves a robust 1 eV trap depth and demonstrates high reproducibility with low alignment error, offering a viable path toward large-scale trapped-ion quantum computing.
This paper reports experimental evidence that a laser-driven dense ensemble of Rb atoms emits light with non-Gaussian statistics, characterized by high-order correlations in the steady state despite the absence of first-order coherence.
This paper presents a theoretical study of periodic superradiance in an Er:YSO crystal using a Maxwell-Bloch model, which successfully derives analytical expressions for the phenomenon's characteristics but reveals that standard experimental parameters fall outside the required regime, suggesting that additional mechanisms, such as field-dependent decay rates, are necessary to fully explain the observations.
This paper introduces a new algorithm utilizing analytical derivatives within the method of continued fractions to accurately compute eigenvalues for generalized spheroidal wave equations with real and complex parameters, demonstrating its efficacy through applications to quasimolecular systems like , , and .
This paper presents an in situ method for measuring and correcting wavefront-induced systematic biases in Mach-Zehnder atom interferometers by introducing controllable curvature to the Raman light, thereby enabling absolute gravitational acceleration measurements with uncertainties below the nm/s² level.
This paper investigates immiscible-to-miscible quenching instabilities in two-dimensional binary Bose-Einstein condensates of rubidium isotopes, revealing that the transition dynamics are driven by vortex production and sound waves, exhibit a bottleneck effect deviating from classical Kolmogorov turbulence scaling, and ultimately stabilize into a linear relationship between the miscibility parameter and the initial configuration.
This paper demonstrates sub-Doppler laser cooling and long-distance optical transport of cesium atoms to 17 µK using a fully static magnetic-field configuration with a blue-detuned Type-II magneto-optical trap, thereby enabling continuous-operation architectures for quantum sensing and computing without the need for time-varying magnetic fields.
This paper outlines a modern, transparent, and methodologically robust effort to improve the precision and reliability of nuclear charge radii determinations by integrating complementary experimental techniques with advanced theoretical frameworks.
This study investigates slow Ar-CO collisions and reveals a strong correlation between the excitation of the scattered projectile and the target ion, where differences in kinetic energy release distributions for varying charge states suggest that projectile autoionization and target excitation are intrinsically linked.
