Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper presents a high-flux cold strontium source utilizing a 2D MOT and Zeeman slower that achieves a record loading rate of atoms/s into a 3D MOT, demonstrating compatibility with long-term operation and state-of-the-art quantum experiments while offering the design freely to the community.
This paper presents a high-flux, vacuum-compatible re-entrant strontium oven featuring micro-machined nozzles and light-driven flux modulation, which achieves a total flux of atoms/s and extends operational lifetime by using laser heating to dynamically control the atomic beam.
This paper proposes and analyzes a flat-bottomed hollow-beam optical ponderomotive trap driven by a high-power CO laser, which effectively confines ultracold neutral plasmas and Rydberg atoms within a uniform dark region while minimizing collisional absorption to enhance antimatter production and storage.
This paper introduces the adiabatic echo protocol, a robust method for preparing entangled many-body quantum states that suppresses static experimental imperfections through dynamically engineered destructive interference, demonstrating its effectiveness across diverse platforms like Ising spin chains and Rydberg atom arrays.
This paper presents the design and characterization of an open-hardware, 19-inch rack-mounted high-power RF amplifier optimized for ultracold atom experiments, delivering 36.5 dBm output across 50–1000 MHz with 40 dB gain, over 35% efficiency, and 0.01 dBm long-term stability.
This paper proposes a robust, time- and wavelength-multiplexed protocol for remote atom-atom entanglement generation using cavity-assisted photon scattering, which achieves a high success rate of and 0.999 fidelity while remaining resilient to operational imperfections and parameter fluctuations.
This paper presents the design, construction, and successful commissioning of a cryogenic Paul trap at LMU Munich that enables the extraction, purification, and sympathetic laser cooling of Th ions alongside Sr ions, forming mixed-species Coulomb crystals to facilitate future laser excitation of the nuclear isomeric transition.
This paper reports a highly sensitive, miniaturized vapor-cell atomic electrometer operating in the quasi-DC frequency range that achieves a noise floor of 0.2–7.7 mV/m using a bare cell without metal electrodes, thereby enabling high-resolution, non-contact electric field sensing for diverse applications ranging from electronics diagnostics to geoscience.
This paper presents an efficient computational model that incorporates molecular structure effects to accurately determine low-energy muon transfer cross-sections from muonic hydrogen to molecular oxygen, thereby significantly improving agreement with theoretical calculations and aiding the analysis of the FAMU experiment.
Using a zero-range model for -wave interactions, this study demonstrates that the three-body recombination rate constant for identical fermions scales as rather than the conventional , while also deriving a perturbative correction term that significantly refines the temperature and interaction dependence near resonance.
