Nonconservation of parity in atoms

The laser in the axial electric field as a tool to search for P-, T-invariance violation

“…However, this angle can not depend linearly on the electric field. One more additional angle (so-called "base angle" [8]) arises due to inexact perpendicular orientation of the analyzer with respect to the polarization plane of the laser beam.…”

“…These are magnetic dipole and strongly forbidden magnetic transitions. The angle of polarization plane rotation in a cell for the length L is equal to (see [5,6,7,8]):…”

“…The above estimation takes into account the Shiff theorem stating that in nonrelativistic quantum mechanic atom EDM should be zero and only relativistic effects allows it to appear [8]. Relativistic effects are given by the multiplier V 2 /c 2 ∼ Z 2 α 2 [8], where V is the typical electron velocity in atom, Z is the atomic number.…”

“…Relativistic effects are given by the multiplier V 2 /c 2 ∼ Z 2 α 2 [8], where V is the typical electron velocity in atom, Z is the atomic number. However, the Shiff theorem does not concern the "mixing" mechanism, because an atom EDM does not appear in it.…”

“…1) with a gas cell the intensity of a light beam decreases when it propagates in a medium. This restricts the length available for polarization plane rotation measurements [8]. An idea to use a photon trap (resonator) with an amplifier (Fig.…”
