We have employed the method of shelving to measure Zeeman resonances of a single trapped Ba+ ion in low magnetic fields, and have observed radio frequency transitions with linewidths of 5 Hz, limited by magnetic-field noise. We have also observed the

We present the first results of a new search for a permanent electric dipole moment of the ${}^{199}\mathrm{Hg}$ atom using a UV laser. Our measurements give $d{(}^{199}\mathrm{Hg})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}\ensuremath{-}(1.0

We calculate the Zeeman frequency shifts due to interactions with the light in a far-off-resonance optical dipole trap. These shifts are important for potential use of such a trap to search for an atomic permanent electric-dipole moment ~EDM!. We pre

Motivated by the potential use of electromagnetically induced transparency (EIT) to measure atomic parity nonconservation (PNC), we have studied EIT and associated optical rotation for a three-level system in thallium vapor. EIT allows sub-Doppler re

We report an improved measurement of the Land\'e ${g}_{J}$ factor of the $5{D}_{5/2}$ state of singly ionized barium. Measurements were performed on single Doppler-cooled ${}^{138}$Ba${}^{+}$ ions in linear Paul traps using two similar, independent a

We propose a method for measuring the magnetic dipole ($M1$) transition moment of the $6{S}_{1/2}(m=\ensuremath{-}1/2)\ensuremath{\leftrightarrow}5{D}_{3/2}(m=\ensuremath{-}1/2)$ transition in single trapped Ba${}^{+}$ by exploiting different symmetr

Synchronously driven optically pumped atomic oscillators have been used to measure the electric-dipole moment of $^{199}\mathrm{Hg}$ as a test of time-reversal symmetry. Our result, d${(}^{199}$Hg)8.7\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\

We have measured the parity-nonconserving (PNC) optical rotation near the 1.279-\ensuremath{\mu}m $^{3}$${\mathit{P}}_{0}$${\ensuremath{\rightarrow}}^{3}$${\mathit{P}}_{1}$ magnetic-dipole absorption line in atomic lead vapor. We measure the quantity

The electric dipole-forbidden, quadrupole $6{S}_{1/2}\ensuremath{\leftrightarrow}5{D}_{3/2}$ transition in Ba${}^{+}$ near 2051 nm, with a natural linewidth of 13 mHz, is attractive for potential observation of parity nonconservation, and also as a c
