Dressed-State Spectroscopy of Proton Spins in Water Beyond the Rotating-Wave Approximation

Ivo Schulthess, Anastasio Fratangelo, Patrick Hautle +6

The quantum Rabi model provides the framework for describing a two-level system interacting with a strong oscillating field beyond the rotating-wave approximation. We report the fi…

Ultracold neutron energy spectrum and storage properties from magnetically induced spin depolarization

N. J. Ayres, G. Ban, G. Bison +53

We present a novel method for extracting the energy spectrum of ultracold neutrons from magnetically induced spin depolarization measurements using the n2EDM apparatus. This method…

Resonant Cancellation Effect in Ramsey-type Nuclear Magnetic Resonance Experiments

Ivo Schulthess, Ivan Calic, Estelle Chanel +8

We investigate the response of a Ramsey-type experiment on an additional oscillating magnetic field. This superimposed field is oriented in the same direction as the static main ma…

New Limit on Axion-Like Dark Matter using Cold Neutrons

Ivo Schulthess, Estelle Chanel, Anastasio Fratangelo +8

We report on a search for dark matter axion-like particles (ALPs) using a Ramsey-type apparatus for cold neutrons. A hypothetical ALP-gluon-coupling would manifest in a neutron ele…

Measurement of the permanent electric dipole moment of the neutron

C. Abel, S. Afach, N. J. Ayres +81

We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magn…

A Revised Experimental Upper Limit on the Electric Dipole Moment of the Neutron

J. M. Pendlebury, S. Afach, N. J. Ayres +47

We present for the first time a detailed and comprehensive analysis of the experimental results that set the current world sensitivity limit on the magnitude of the electric dipole…
