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…
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…
Constraining interactions mediated by axion-like particles with ultracold neutrons
S. Afach, G. Ban, G. Bison +35
We report a new limit on a possible short range spin-dependent interaction from the precise measurement of the ratio of Larmor precession frequencies of stored ultracold neutrons a…
Limits on the Axial Coupling Constant of New Light Bosons
F. Piegsa, G. Pignol
We report on a neutron particle physics experiment, which provides for the first time an upper limit on the strength of an axial coupling constant for a new light spin 1 boson in t…
