A magnetic environment with reproducible spatio-temporal magnetic conditions at picotesla level
Philipp Wunderl, Maximilian Huber, Florian Büttiker +16
Walk-in, picotesla-scale environments are essential for measurements of biomagnetism and fundamental physics. However, conventional rooms require typical active dynamic compensatio…
Scalar-Magnetometer Search for Ultralight Dark Photon Dark Matter with a Single-Site, Two-Sensor Array: A 6-Channel DTFT Likelihood Analysis with Scalar Optically Pumped Magnetometers
Peisen Zhao, Ole Behrens, Maja Benning +6
We report on a laboratory search for ultralight dark photon dark matter using a single-site, two-sensor scalar magnetometer array. The experiment employs two scalar optically pumpe…
Avoiding Blindness in Baryon Number Violating Processes: Free-Beam and Intranuclear Paths to Neutron-Antineutron Transitions
Joshua L. Barrow, Peter Fierlinger, Yuri Kamyshkov +4
Experimental searches for neutron--antineutron () transitions can be considered via two approaches: conversion in free-neutron beams and intranuclear transfor…
The HIBEAM Instrument at the European Spallation Source
V. Santoro, D. Milstead, P. Fierlinger +61
The European Spallation Source (ESS) will be the world's brightest neutron source and will open a new intensity frontier in particle physics. The HIBEAM collaboration aims to explo…
Detecting the Coupling of Axion Dark Matter to Neutron Spins at Spallation Sources via Rabi Oscillation
Peter Fierlinger, Jie Sheng, Yevgeny V. Stadnik +1
We propose a novel detection method for axion dark matter using the Rabi oscillation of neutron spins in beam-based measurements. If axions couple to neutron spins, a background os…
