Experimental techniques (cryogenic, room temperature, crystal)

Oral

**nEDM as a dark matter detector: constraints on axion-like dark matter from limits on an oscillating EDM** N. J. Ayres for the nEDM collaboration at PSI Axions and axion-like particles (ALPs) are popular dark matter candidates. Ultralight axion and ALP cold dark matter would manifest as a classical field, oscillating coherently on a galactic scale. Through their couplings to gluons,...

EDM experiment overviews

Oral

Neutron electric dipole moment (nEDM) research at the Petersburg Nuclear Physics Institute (PNPI) in Gatchina, Russia, is briefly reviewed and the present and near future programme led by PNPI at the Institut Laue Langevin (ILL) in Grenoble, France, outlined.

7. Hunting the nedm by random walks

Prof. Robert Golub (NCSU)

Systematic effects

Oral

The behavior of a spin undergoing Larmor precession in the presence of fluctuating fields is of interest to workers in many fields. Particles making random walks in inhomogeneous fields see time fluctuating fields which cause frequency shifts and relaxation which are related to their power spectrum, which can be determined by taking the Fourier transform of the auto-correlation functions of...
