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 study demonstrates that subcycle phase matching effects, revealed through two-color laser-assisted photoionization of HHG-generated attosecond pulse trains, cause unexpected spectral redistributions dependent on the carrier-to-envelope phase that cannot be explained by single-atom responses alone.
This paper proposes that relic neutrinos from the Big Bang can be detected via parametric fluorescence, a coherent scattering process in atomic or molecular systems where a massive neutrino decays into a lighter neutrino and a signal photon, offering a promising detection method with event rates potentially reaching one per year in optimized target volumes.
This paper presents a numerical study demonstrating that controlled non-adiabatic dynamics, specifically synchronized with intra-site breathing oscillations, enable fast momentum-selective transport of Bose-Einstein condensates in optical lattices with high fidelity and narrow momentum distributions, offering a significant speedup over traditional adiabatic protocols for quantum sensing applications.
This paper demonstrates that electric fields can systematically control atom-molecule Feshbach resonances in ultracold sodium-potassium mixtures, revealing distinct trimer bound states and providing a new method for manipulating polyatomic quantum matter.
This study experimentally validates theoretical models linking control signal amplitude noise to qubit state fidelity in a 10x10 neutral atom array, demonstrating strong agreement between measured results and stochastic Schrödinger equation predictions to aid noise identification and optimal control in NISQ-era systems.
This paper reports the first observation of interaction-induced, continuously tunable Fermi surface deformations in a deeply degenerate gas of microwave-shielded polar molecules, demonstrating a highly controllable platform for exploring strongly correlated dipolar quantum matter.
This paper introduces a rapid spectroscopic technique based on dimer-projection to measure contact parameters in a unitary Fermi gas on microsecond timescales, revealing that this feature dominates the clock shift and highlighting the significance of multichannel effects beyond universal predictions.
This paper establishes a unified framework for realizing shortcuts to adiabaticity by demonstrating that adaptive quantum Zeno measurements, whether stroboscopic or continuous, generate an effective Hamiltonian containing a nonadiabatic geometric connection that naturally reduces to counterdiabatic driving when measurements are performed in the system's instantaneous energy eigenbasis.
This paper presents new R-matrix and MCDHF atomic data for tellurium ions (Te I–V), including electron-impact excitation and photoionization cross-sections, to improve kilonova spectral modeling and investigate Te IV's potential contribution to the 1.08 μm emission feature in AT2017gfo.
This paper presents a compact 44-cm dual-beam Zeeman slower design that utilizes oblique laser beams and a capillary-array collimation system to significantly enhance cold atom flux for 2D-MOT loading while nearly eliminating window contamination, as validated by simulations and experiments with Rubidium and Ytterbium.
