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.
At Gist.Science, we track every new preprint in this field as it appears on arXiv, ensuring you stay ahead of the curve. 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 study demonstrates that applying a trigger laser tuned to the superradiance transition wavelength in an Er:YSO crystal enables precise control over both the period and timing of triggered periodic superradiance by lowering the emission threshold and reducing variance, a phenomenon validated by Maxwell-Bloch simulations.
This paper presents a general in-situ method that cancels differential light shifts in trapped-atom microwave clocks by interrogating multiple atomic ensembles at varying trap intensities and extrapolating their frequency measurements to the zero-intensity limit, thereby achieving shot-to-shot stability without requiring magic wavelengths or species-specific schemes.
This paper reports a wideband search for ultralight axionlike dark matter using oscillating parity-odd time-reversal-odd nuclear Schiff moments in Eu ions within a crystal, resulting in new constraints on ALP-gluon coupling strength across eight decades of mass.
This paper investigates the dynamics of water molecule fragmentation induced by intense X-ray radiation by calculating oxygen ion charge distributions, constructing Newton diagrams for dissociation products, and evaluating released kinetic energy to predict outcomes under various pulse parameters.
This paper refutes the proposal that alkali Rydberg atoms can be trapped in attractive, far-detuned, monochromatic optical fields by demonstrating through analytic derivation and experimental measurement that the vector polarizability is negligible at large detunings, thereby confirming that such attractive traps are impossible regardless of beam geometry.
This paper proposes using precision spectroscopy of paramagnetic lanthanide and actinide ions doped in noncentrosymmetric crystals as a highly sensitive platform to detect time-reversal symmetry-violating nuclear moments, potentially improving constraints on new physics by two orders of magnitude.
This paper presents a comparative study of self-energy corrections to ionization energies in sodium-like ions using rigorous bound-state QED and model-QED-operator approaches, demonstrating their good agreement and validating the efficiency of the latter method for many-electron systems.
This paper reports the successful development and sea-trial of a portable ytterbium-171 optical atomic clock that achieves high-frequency stability () by interrogating an ultra-narrow optical transition using a transversely-cooled thermal atomic beam, demonstrating its viability for GNSS-independent timekeeping in dynamic environments.
This paper demonstrates that both perturbative and all-order relativistic approaches yield consistent ground-state binding energies for muonic beryllium to within one part per million, thereby providing a precise parametrization for extracting the Be charge radius and bridging theoretical methodologies between light and heavy muonic systems.
This study employs high-accuracy ab initio calculations and full quantum scattering theory to investigate the radiative association of Ag and H into AgH, revealing that the X channel dominates at low energies and providing essential thermal rate coefficients for modeling transition-metal hydride formation in cold astrophysical environments.
