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.
The researchers theoretically propose and experimentally demonstrate a high-efficiency, cavity-free microwave-to-optical transducer using a Rydberg ensemble that utilizes cascaded electromagnetically induced transparency to store and convert microwave photons into optical photons for quantum repeater applications.
This study demonstrates that inhomogeneous strain induced by creases in freestanding and membranes significantly suppresses local thermal conductivity by broadening phonon dispersion and enhancing scattering rates, offering a potential mechanism for developing active thermal management devices.
This paper demonstrates that two-photon-excited fluorescence spectroscopy of and atoms in a magneto-optical trap allows for the observation of sensitive spectral signatures at extremely low photon fluxes due to the negligible Doppler broadening achieved through optical cooling.
This paper reports the observation and characterization of three narrow, semi-forbidden electric quadrupole transitions in excited ions, providing detailed measurements of their frequencies, hyperfine structures, and lifetimes to complement existing quantum information and fundamental physics research.
This paper demonstrates the simultaneous transverse laser cooling and Zeeman-hyperfine optical pumping of a thermal dysprosium atomic beam to a specific polarized ground state using a single 421 nm laser, preparing the system for fundamental physics experiments such as parity violation measurements.
This paper presents hyperfine-resolved optical spectroscopy of ultracold RbCs molecules in the metastable state, utilizing a theoretical model to extract coupling constants and Rabi oscillation measurements to determine transition dipole moments and spontaneous emission rates.
This paper resolves the hyperfine puzzle in hydrogen, which suggests a variational collapse due to a energy term, by demonstrating that accounting for the proton's finite size yields a stable ground state with a radius indistinguishable from the Bohr radius.
This paper demonstrates that periodically driven quantum rotors serve as a versatile platform for realizing anomalous multi-gap topological phases, characterized by non-Abelian band braiding that stabilizes nodal lines and gives rise to a unique out-of-equilibrium Dirac string phase with distinct edge states.
This study investigates the low-energy electron-induced dissociation of 1-propanol by identifying four distinct anion fragments and their energy-dependent yields, which, when supported by Density Functional Theory calculations, reveal site-specific fragmentation pathways consistent with previously studied alcohols.
This paper presents a polymer self-consistent field theory for atoms using Gaussian basis functions and an excluded-volume model to enforce the Pauli-exclusion principle, successfully calculating binding energies and electron densities for elements from hydrogen to krypton while recovering standard quantum mechanical limits.
