2 4 Ju n 19 99 Enhancement of parity and time invariance violation in Radium atom
نویسنده
چکیده
There are several factors which lead to a huge enhancement of parity and time invariance violating effects in the Ra atom: very close electronic levels of opposite parity, the large nuclear charge Z and the collective nature of T,P-odd nuclear moments. Experiments with Radium may be used to measure it's nuclear anapole, magnetic quadrupole and Schiff moments. Such measurements provide information about parity and time invariance violating nuclear forces and electron-nucleon interactions.

ec 1 99 9 Calculation of parity and time invariance violation in the radium atom
Calculation of parity and time invariance violation in the radium atom. Abstract Parity (P) and time (T) invariance violating effects in the Ra atom are strongly enhanced due to close states of opposite parity, the large nuclear charge Z and the collective nature of P, T-odd nuclear moments. We have performed calculations of the atomic electric dipole moments (EDM) produced by the electron EDM ...

If electrons had an electric dipole moment (EDM) they would induce EDMs of atoms. The ratio of the atomic EDM to the electron EDM for a particular atom is called the enhancement factor, R. We calculate the enhancement factor for the francium and gold atoms, with the results 910± ∼ 5% for Fr and 260± ∼ 15% for Au. The large values of these enhancement factors make these atoms attractive for elec...

We show for the first time that the induced parity–even Lorentz invariance violation can be unambiguously calculated in the physically justified and minimally broken dimensional regularization scheme, suitably tailored for a spontaneous Lorentz symmetry breaking in a field theory model. The quantization of the Lorentz invariance violating quantum electrodynamics is critically examined and shown...

We give a pedagogical discussion of how color superconductivity can produce parity violation in cold quark matter at very high densities. In this note, we give a pedagogical discussion of how, for massless quarks at very high densities, the formation of a spin-zero color superconducting condensate spontaneously breaks both the axial U(1) symmetry and parity [1]. This observation is implicit in ...
