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.
Using data from the Chang'e-6 lander's NILS instrument, this study employs a novel semi-analytical model to quantify the scattering and sputtering of solar wind protons on the lunar surface, revealing specific probabilities for negative ion emission, the influence of surface roughness on angular distributions, and a surface binding energy of 5.5 eV.
This paper reports the first generation of a fully distributed Greenberger-Horne-Zeilinger (GHZ) state across a three-node quantum network of single atomic memories using photonic interconnects, achieving high fidelity and a clear violation of Mermin's inequality while closing the detection loophole.
This paper proposes a method for neutral atom quantum computing platforms that utilizes stroboscopic Rydberg dressing to collectively squeeze interatomic distance fluctuations and generate non-classical motional states, thereby reducing gate infidelities and motional decoherence.
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.
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.
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.
This paper reports the experimental observation of interaction-enabled topological pumping in a synthetic lattice of correlated Rydberg electrons, demonstrating how tunable dipolar exchange interactions can shift topological singularities to drive successive transitions between quantized and non-quantized transport regimes.
This paper proposes a joint spectroscopy scheme using two highly charged 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 Th nuclear optical clock.
This review surveys recent experimental advances in four major classes of ultracold atomic lattice platforms—optical lattices, synthetic lattices, Floquet-engineered lattices, and optical tweezer arrays—highlighting their distinct capabilities for realizing and probing topological phases while discussing emerging directions and future prospects in the field.
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.
