Parity nonconservation in odd isotopes of single trapped atomic ions

Abstract

We have estimated the size of the light shifts due to parity-nonconservation (PNC) interactions in different isotopes of Ba${}^{+}$ and Ra${}^{+}$ ions based on the work of Fortson [Phys. Rev. Lett. 70, 2383 (1993)]. We have used the nuclear-spin-independent (NSI) amplitudes calculated earlier by us [Phys. Rev. Lett. 96, 163003 (2006); Phys. Rev. A 78, 050501(R) (2008)], and we have employed the third-order many-body perturbation theory [MBPT(3)] in this work to estimate the nuclear-spin-dependent (NSD) amplitudes in these ions. Ra${}^{+}$ is found to be more favorable than Ba${}^{+}$ for measuring both the NSI and NSD PNC observables.
