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 proposes a novel method using cryogenic microcalorimeters to perform precision muonic x-ray spectroscopy of light transition elements, aiming to reduce the uncertainty in their absolute electric quadrupole moments by an order of magnitude to significantly advance nuclear structure studies and quantum chemistry benchmarks.
This paper demonstrates the first three-dimensional magneto-optical trapping of the metal hydride molecule CaH, achieving temperatures below one millikelvin and opening a pathway for the optical trapping of hydrogen atoms via controlled molecular dissociation.
This paper reports the successful realization of two-dimensional magnetically-assisted Sisyphus laser cooling for the asymmetric top molecule calcium monoamide (CaNH), demonstrating effective vibrational and rotational state closure that expands the scope of molecular laser cooling to the most complex geometric class of molecules for future quantum applications.
This paper presents a miniaturized, optically-heated neutral atom source that achieves rapid all-optical loading of trapped ions, demonstrating single-ion loading in under 30 seconds with low optical power and establishing a thermal model to guide future performance improvements.
This paper presents a Rydberg-atom electric field sensor utilizing a sapphire vapor cell to overcome RF screening limitations and detect sub-100 MHz signals, demonstrating its performance in the ISM band alongside a shared Python-based routine for optimizing off-resonant detection parameters.
This paper proposes a dual metastable-state encoding architecture for neutral-atom arrays that leverages distinct nuclear-spin and hyperfine-spin qubit subspaces to enable long-coherence storage, fast operations, and mid-circuit measurement without disturbing data qubits, thereby providing a scalable framework for fault-tolerant quantum error correction.
This paper introduces "quantum hodographs" as universal topological descriptors for non-stationary quantum dynamics, demonstrating that expectation value trajectories in systems like free electrons and anisotropic oscillators form robust knots and loops with winding numbers that can be experimentally reconstructed via optical modulation spectroscopy.
This paper systematically maps the four-dimensional parameter space of double microwave shielding to identify optimal operating regimes that maximize loss suppression and interaction tunability for polar molecules, ultimately identifying heavy, strongly dipolar species as the most promising candidates for future quantum simulation experiments.
Using explicitly correlated basis functions, this study calculates the Born-Oppenheimer potential curves for excited states of the hydrogen-antihydrogen system, demonstrating that these states support ro-vibrational levels near the dissociation threshold and must therefore be included in theoretical models of ground-state collisions.
This paper demonstrates that collective emission effects, such as resonance shifts and directional coherent emission, can be preserved in subwavelength arrays of solid-state silicon-vacancy centers despite severe inhomogeneous broadening by utilizing high-density ion implantation to create "superatoms" that achieve probabilistic frequency matching.
