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…
Simulation and optimization of the Active Magnetic Shield of the n2EDM experiment
N. J. Ayres, G. Ban, G. Bison +47
The n2EDM experiment at the Paul Scherrer Institute aims to conduct a high-sensitivity search for the electric dipole moment of the neutron. Magnetic stability and control are achi…
Fundamental Nuclear and Particle Physics At Neutron Sources
H. Abele, J. Amaral, W. R. Anthony +121
Fundamental neutron and neutrino physics at neutron sources, combining precision measurements and theory, can probe new physics at energy scales well beyond the highest energies pr…
