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.

Momentum and Matter Matter for Axion Dark Matter Matters on Earth

This paper investigates how Earth's matter effects and the finite momentum of axion dark matter influence experimental searches, finding that while canonical axion models remain largely unaffected, lighter axions with stronger couplings may experience reduced field values but enhanced spatial gradients, significantly altering detection sensitivity.

Superfluid Fraction of a 2D Bose-Einstein Condensate in a Triangular Lattice

This paper experimentally determines the superfluid fraction of a two-dimensional Bose-Einstein condensate in a triangular optical lattice using two consistent methods—hydrodynamic analysis of in situ density profiles and dynamical measurements of compressibility and sound velocity—which align with Gross-Pitaevskii simulations and Leggett bounds.

Programmable Gauge-Field Textures with Ultracold Atoms in Momentum Space

This paper experimentally demonstrates a highly programmable two-dimensional momentum-state lattice of ultracold atoms that enables the creation of spatially structured synthetic gauge fields, allowing for the observation of flux-modified transport dynamics, Hall-type drift, and anisotropic propagation along engineered flux domain walls.

Simultaneous Determination of Multiple Nuclear Parameters of 229^{229}Th Using Highly Charged Ions

This paper proposes a joint spectroscopy scheme using two highly charged 229^{229}Th ions to simultaneously determine five key nuclear parameters without external inputs, thereby significantly reducing uncertainties in the nuclear transition energy and charge-radius difference to advance the development of a 229^{229}Th nuclear optical clock.

Quantum enhancement and Doppler suppression of Kasevich-Chu atom interferometer with motional squeezing states

This paper demonstrates that introducing motional squeezing states into a Kasevich-Chu atom interferometer significantly enhances sensitivity and robustly suppresses Doppler effects, offering a viable path for high-precision gravimetry on mobile platforms where internal spin entanglement is compromised by decoherence.

Bandstructure of a coupled BEC-cavity system: effects of dissipation and geometry

This paper presents a theoretical model based on band structure and mean-field theory to analyze a transversally driven Bose-Einstein condensate coupled to an optical cavity, revealing how dissipative couplings and geometric deviations from a 90-degree angle induce non-Hermitian phenomena like exceptional points and precursor mode coalescence that govern the system's superradiant phase transition.
