“…An example of the magnetometers' versatile nature is a Cs magnetometer constructed at Amherst. It was used to set a limit on parity (P) and time-reversal invariance (T) violating electron electric dipole moment (EDM) d that generates d E · S coupling [65], on violation of Lorentz invariance manifested as a spin coupling b · S to a background vector field b [66], and on spin-dependent forces that can be mediated by axions [67].…”

Some of the most sensitive methods of measuring magnetic fields utilize interactions of resonant light with atomic vapor. Recent developments in this vibrant field are improving magnetometers in many traditional areas such as measurement of geomagnetic anomalies and magnetic fields in space, and are opening the door to new ones, including, dynamical measurements of bio-magnetic fields, detection of nuclear magnetic resonance (NMR), magnetic-resonance imaging (MRI), inertialrotation sensing, magnetic microscopy with cold atoms, and tests of fundamental symmetries of Nature.

“…−26 e cm [17], which implies Θ ≃ 10 −4 if the effective dipole length of electrons l e ≃ G F m e ≃ 10 −22 cm is used. A possible leptonantilepton asymmetry is suggested as a consequence of C, T, and CP violation during the DSSB of the SU (3) I symmetry to the SU (2) L × U (1) Y symmetry: the electron asymmetry δ e ≃ 10 −7 [18,19] is suggested as a consequence of the U (1) Y gauge theory.…”

Quantum weakdynamics (QWD) as an SU (3)I gauge theory with the Θ vacuum term is considered to be the unification of the electroweak interaction as an SU (2)L × U (1)Y gauge theory. The grand unification of SU (3)I × SU (3)C beyond the standard model SU (3)C × SU (2)L × U (1)Y is established by the group SU (3)I . The grand unified interactions break down to weak and strong interactions at a new grand unification scale 10 3 GeV, through dynamical spontaneous symmetry breaking (DSSB); the weak and strong coupling constants are the same, αi = αs ≃ 0.12, at this scale. DSSB is realized by the condensation of scalar fields, postulated to be spatially longitudinal components of gauge bosons, instead of Higgs particles. Quark and lepton family generation, the Weinberg angle sin 2 θW = 1/4, and the Cabbibo angle sin θC = 1/4 are predicted. The electroweak coupling constants are αz = αi/3, αw = αi/4, αy = αi/12, and αe = αi/16 ≃ 1/137; There are symmetric isospin interactions.

“…Inserting (11) in (12), multiplying the resulting equations on the left by urn·' where m=-1,O,1, and dropping all rapidly oscillating terms, (adiabatic approximation). we obtain: am = -{umlliro} m= 1,0,-1 (13) am Now inserting (10) into (13) we carry out a simple calculation to arrive at:…”

“…The present investigation is thus of interest in connection with CP violation. Indeed, a number of theoretical models of CP violation have recently appeared 1 -4 that predict the existence of an electron EDM in the range [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] _10-27 e cm, possibly large enough to be detected in a practical experiment.…”
