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 paper demonstrates efficient three-dimensional sub-Doppler cooling of a single Ca ion in a Penning trap by utilizing a narrow two-photon dark resonance and a parametric drive to exchange energy between axial and radial modes, achieving a final mean thermal occupation of 1.5(3) within 800 s even outside the Lamb-Dicke regime.
This paper introduces a robust, all-optical laser trap that uses collimated beams to capture and cool over one million neutral rubidium atoms from background vapor to densities and temperatures comparable to magneto-optical traps, but without requiring any magnetic fields.
This paper presents a single printed-circuit-board-based linear Paul trap for electrons that eliminates assembly requirements and manufacturing tolerances, achieving electron lifetimes of 2.13 ms and secular frequencies up to 90 MHz to support spin-based quantum information processing.
This paper demonstrates the generation and control of Schrödinger cat states in the quantized motion of a single neutral atom trapped in an optical tweezer by exploiting the system's intrinsic self-Kerr nonlinearity, offering a robust, spin-independent framework for bosonic-state engineering and quantum error correction.
This paper proposes a high-fidelity hybrid qubit-oscillator platform using the motional states of two interacting atoms in an optical tweezer, which enables versatile bosonic operations and achieves sub-Hz resolution for detecting magnetic dipolar interactions within a tweezer array.
This paper calculates parity-violating E1 amplitudes for specific transitions in highly charged calcium and lead ions, demonstrating that neutron-skin corrections can be neglected for the calcium isotope pair (making it advantageous for searching for new boson physics) while remaining significant for lead.
This paper experimentally demonstrates that ultracold Rydberg gases, equipped with a controlled gain mechanism to mimic metabolic resource replenishment, serve as a highly controllable simulator for investigating neural network criticality, revealing key phenomena such as power-law avalanche scaling, universal shape collapse, and stochastic oscillations in a non-equilibrium steady state.
This paper develops a quantum model for levitated ferromagnetic gyroscopes that reveals discrete precessional and librational states, enabling the use of these systems as controllable mesoscopic quantum platforms for ultrasensitive sensing and searches for new physics.
This paper proposes that measuring parity non-conservation in hydrogen transitions involving higher-wave states (where the standard model contact interaction is suppressed) offers a significantly enhanced sensitivity to detecting light bosons predicted by unification models.
This paper proposes a correlated comagnetometry technique using two alkali species in a single cell to achieve calibration-free, high-frequency magnetic noise cancellation, thereby significantly enhancing sensitivity and enabling model differentiation for precision measurements and exotic field detection.
