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 that high-fidelity control of metastable trapped-ion qubits enables erasure conversion of spontaneous scattering errors, achieving a SPAM-corrected Bell state fidelity of 98.61% (99.16% after erasure subtraction) to support low-overhead, fault-tolerant quantum computing.
This paper experimentally realizes a continuum analog of the Hatano-Nelson model in a spin-orbit coupled Bose-Einstein condensate by introducing tunable spin-dependent loss, demonstrating collective nonreciprocal transport and self-acceleration while revealing how strong interactions suppress topological edge states in favor of localized excited states.
The authors demonstrate a continuous cloud position spectroscopy technique using a broadband magneto-optical trap on strontium's intercombination line that achieves frequency instability below after 400 seconds, surpassing conventional hot-vapor methods by combining high sensitivity with a large locking range.
This paper derives and numerically validates an analog of the Lellouch-Lüscher relation for few-body bosonic systems, establishing a robust framework to link harmonically trapped state properties to scattering loss rates and enabling precise determination of multi-body scattering rates in confined ultracold experiments.
This paper introduces a full-quantum algorithm that transforms time-dependent variational dynamics into static linear equations via Chebyshev spectral discretization and solves them using quantum singular value transformation, thereby eliminating classical feedback, achieving exponential convergence for smooth Hamiltonians, and enabling time-step-independent circuit depths for both fault-tolerant and near-term quantum devices.
This paper demonstrates a simplified experimental protocol for producing a Bose-Einstein condensate using a single pair of crossed wires on an atom chip, which serves as both the magneto-optical trap for capturing over 10^8 atoms and the magnetic trap for evaporative cooling to achieve a condensate of over 10^4 atoms.
This paper theoretically demonstrates a non-perturbative scheme using isolated attosecond pulses to recover the photoelectron spectral phase via coherent interference, thereby enabling the time-resolved observation of electron birth processes and energy-time correlations in strong-field ionization.
This paper presents the design and implementation of a robust, modular, and compact Class 1 laser system for atom-based quantum technologies, featuring 13 wavelengths from 375 nm to 1092 nm, high transmission efficiencies of 21–28%, and sub-MHz stabilization linewidths within a single server rack.
This paper reviews the formation and properties of ultradilute quantum liquid droplets stabilized by quantum fluctuations in bosonic mixtures and dipolar gases, while also exploring the emergence and characteristics of supersolidity in both dipolar systems and spin-orbit-coupled mixtures.
This paper theoretically investigates the rotational excitation of asymmetric-top molecular ion isotopologues HO, HDO, and DO by electron impact using a combined framework of R-matrix scattering, multichannel quantum-defect theory, and adapted frame transformation and Coulomb-Born approximations to provide state-resolved cross sections and kinetic rate coefficients.
