Neutron electric dipole moment and dressed spin
The neutron electric dipole moment (EDM) experiment has played a unique role in examining the violation of fundamental symmetries and understanding the nature of electroweak and strong interaction. A non-zero neutron EDM is one of direct evidence for CP and T violation and has the potential to …

Magnetic fields and ultracold neutron production: studies towards the neutron electric dipole moment experiment at TRIUMF
The existence of a non-zero neutron electric dipole moment (nEDM) confirms the theoretical models of Physics beyond the Standard Model which provide extra sources of CP violation. Based on Sakharov Criteria, CP violation is one of the main ingredients to create the baryon asymmetry in the universe. …

Measurement of wall relaxation times of polarized 3He in bulk liquid 4He for the Neutron Electric Dipole Moment experiment
The Neutron Electric Dipole Moment (nEDM) experiment that will take place at the Spallation Neutron Source (SNS) in Oak Ridge, Tennessee will measure the electric dipole moment (EDM) of the neutron with a precision of order 10-28 e-cm, utilizing spinpolarized 3He in bulk liquid 4He to detect …

Measurement of Wall Relaxation Times of Polarized Helium-3 in Bulk Liquid Helium-4 for the Neutron Electric Dipole Moment Experiment
The relaxation rates extrapolated from the observed values of Pd for d-TPB, coated Torlon, and coated BeCu in the nEDM apparatus were found to be consistent with design goals.

Spontaneous CP-Violation in Two Higgs Doublet Supersymmetric Models
… effects in the kaon systems and a nonzero neutron electric dipole moment are studied.

Violation of CP invariance in weak interactions
… rate of the CP violating process K2 -> 2pi. The neutron electric dipole moment, which depends on the violation of space-reflection invariance and of time-reversal invariance, is also calculated. It is found that in this theory the selection rule Delta S [not equal] +/- 2 has as a consequence the …

Holographic and Composite Models of the Axion
… axion, first proposed to solve the absence of a neutron electric dipole moment, is also an excellent dark matter candidate. If the axion is composite, it must be bound by a novel strong interaction. Some strongly-coupled models, mathematically intractable until now, are recently discovered to be …

Transport of 3He for the nEDM experiment at the SNS
The neutron electric dipole moment (nEDM) experiment at the Spallation Neutron Source (SNS) will measure the electric dipole moment (EDM) of the neutron with a precision of 5.4\times10^{-28}\,\mathrm{e\cdot cm}. This experiment utilizes polarized 3He in superfluid 4He to detect neutron precession …

NV diamond project for nEDM
… as metrological sensors for measuring both, electric and magnetic fields at room temperature and also at 4 K. This thesis discusses different techniques used to probe the NV centers electronic structure. The first, Optically Detected Magnetic Resonance (ODMR) allows us to probe the Zeeman and …
