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 experimentally determines the ground-state scalar and vector polarizabilities of Dy near 530 nm by exploiting strong spin-dependent light shifts, providing results that agree with theoretical calculations and offering essential data for optimizing single-atom trapping in optical tweezer arrays.
This paper presents a scalable infrastructure for strontium optical clocks that integrates photonics, metasurface optics, and nonlinear frequency combs to replace bulky free-space laser setups, successfully demonstrating robust magneto-optical traps for all stable strontium isotopes.
This paper presents a theoretical study demonstrating that strongly interacting Rydberg polaritons exhibit a warped multiband dispersion with degenerate Dirac points and rotational symmetry, challenging the conventional single-band parabolic approximation and advancing the understanding of multi-photon quantum correlations.
This paper presents a low-frequency electric field sensor using a collimated Rydberg atomic beam and ionization detection, which mitigates surface screening effects to achieve a sensitivity better than 1 mV/m for frequencies above 20 Hz and a linear dynamic range exceeding 50 dB.
This paper demonstrates that strong-field ionization in circularly polarized laser fields generates a photoelectron spin torus in momentum space, whose rotation angle and splitting provide a robust, self-referenced method for measuring attosecond time delays and intermediate-state dynamics beyond conventional momentum spectroscopy.
This paper provides a detailed description of a method for calculating high-order QED vacuum polarization corrections up to order in the Coulomb field of a pointlike nucleus by reducing the problem to free QED Feynman graphs with up to eight independent loops.
This paper explores the unique properties and experimental potential of strongly dipolar molecular Bose-Einstein condensates, outlining achievable parameter regimes, suitable molecular species, and the extension of beyond mean-field theories to advance the understanding of dipolar quantum fluids and exotic many-body states.
This paper demonstrates the fabrication of robust, long-lasting, and ultra-high vacuum atomic beam and vapor cells using wafer-scale plastic deformation micro-knife bonding of fused silica, offering a scalable pathway for advanced chip-scale quantum devices.
This paper demonstrates the use of ultracold RbCs molecules to encode a 1D synthetic lattice in their rotational states, successfully realizing the Su-Schrieffer-Heeger model with long coherence times and full site-resolved readout to probe and verify the stability of topological edge states against various perturbations.
This paper demonstrates that transverse fields, which inevitably accompany static field gradients, cause significant variations in the sensitivity and fringe visibility of three-dimensional Stern-Gerlach interferometers, implying that only specific implementation sequences can achieve high-precision measurements with ultracold Rydberg atoms.
