Semi-empirical calculations for a new scheme to probe atomic parity violation using Sn

ORAL

Abstract

Previously, we presented numerical simulations to validate a novel scheme for laser cooling and trapping of Group IV atoms [1]. Here, we focus on the application of this scheme to optical lattice trapping of tin (Sn) atoms for an atomic parity violation measurement. We present semi-empirical estimates of the dynamic polarizabilities of various states with the 5s25p2 configuration in Sn, as well as the parity violating (PV) induced E1 transition amplitude of the 5s25p2 3P1 to 5s25p2 1S0 clock transition. We further outline an experimental scheme where an isotope chain of laser-cooled and optically trapped Sn atoms can be used as a sensitive probe of electroweak nuclear physics and certain theories of physics beyond the Standard Model.
