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.
By periodically modulating the trapping potential of a spherical unitary Fermi gas to excite a dissipationless breathing mode via SO(2,1) symmetry, researchers precisely measured the system's nonequilibrium energy evolution, revealing that trapping and internal energies oscillate out of phase and are governed by the dynamic virial theorem rather than equilibrium predictions.
This paper proposes a novel scheme for detecting wave-like dark matter, specifically dark photons, by utilizing large ensembles of Rydberg atoms trapped in optical tweezer arrays to observe DM-induced excitations between energy levels, with the ability to scan different dark matter masses via external magnetic field tuning.
This paper calculates parity non-conserving transition amplitudes in Rubidium and Strontium ions to demonstrate that lighter atomic systems offer enhanced sensitivity and theoretical precision for detecting low-mass vector bosons compared to heavier elements like Cesium.
This paper introduces QOuLiPo, a framework that maps classical texts to neutral-atom quantum processors via graph representations to define a structural rigidity metric, generate engineered texts as scalable benchmarks, and demonstrate high-fidelity execution on the Pasqal FRESNEL hardware.
This paper outlines the scientific potential and practical feasibility of deploying a long-baseline atom interferometer at the South Pole to detect decihertz gravitational waves, leveraging the site's unique low seismic noise and infrastructure to enhance global detector networks and fundamental physics tests.
This paper introduces and summarizes recent experimental results for two primary radiation thermometry standards, the cold atom thermometer (CAT) and the compact blackbody radiation atomic sensor (CoBRAS), which utilize laser-cooled and vapor-phase rubidium atoms to measure blackbody radiation rates for precise temperature determination.
This study investigates the decay dynamics of optically trapped ultracold Dy-K Feshbach molecules across various wavelengths, identifying light-induced losses as the dominant mechanism except near 2000 nm, where inelastic collisions become observable and Pauli suppression significantly reduces collisional losses for weakly bound dimers.
This study demonstrates that the tilt of photoelectron momentum distributions in XUV ionization is governed not only by magnetic quantum numbers but also by the radial structure of atomic orbitals, revealing a wavelength-dependent tilt reversal in argon caused by Cooper-like suppression in the -wave channel due to the 3p orbital's radial node.
This paper presents an all-optical method using spatially selective parametric heating in a passively stabilized beat-note superlattice to deterministically isolate single or bilayer samples of cold dipolar atoms, enabling high-resolution microscopy of long-range interacting systems.
This paper derives a quantum Brownian motion master equation describing the decoherence of a particle's spatial superposition along stationary worldlines in the Minkowski vacuum, identifying two thermal-like contributions arising from the modified field spectrum observed by the particle and differential time dilation across its wavefunction, with specific rates evaluated for hyperbolic and uniform circular motion.
