Magnetic trapping of atomic nitrogen and cotrapping of imidogen

We observe magnetic trapping of atomic nitrogen $(^{14}\mathrm{N})$ and cotrapping of ground-state imidogen ( $^{14}\mathrm{N}\mathrm{H}$ , $X\phantom{\rule{0.2em}{0ex}}^{3}\ensuremath{\Sigma}^{\ensuremath{-}}$). Both are loaded directly from a room-temperature beam via buffer gas cooling. We trap approximately $1\ifmmode\times\else\texttimes\fi{}{10}^{11}$ $^{14}\mathrm{N}$ atoms at a peak density of $5\ifmmode\times\else\texttimes\fi{}{10}^{11}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$ at $550\phantom{\rule{0.3em}{0ex}}\mathrm{mK}$ . The $12\ifmmode\pm\else\textpm\fi{}4\phantom{\rule{0.3em}{0ex}}\mathrm{s}$ $1∕e$ lifetime of atomic nitrogen in the trap is consistent with a model for loss of atoms over the edge of the trap in the presence of helium buffer gas. Cotrapping of $^{14}\mathrm{N}$ and $^{14}\mathrm{N}\mathrm{H}$ is accomplished, with ${10}^{8}$ NH trapped molecules at a peak density of ${10}^{8}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$.We observe magnetic trapping of atomic nitrogen $(^{14}\mathrm{N})$ and cotrapping of ground-state imidogen ($^{14}\mathrm{N}\mathrm{H}$, $X\phantom{\rule{0.2em}{0ex}}^{3}\ensuremath{\Sigma}^{\ensuremath{-}}$).

Optical spin readout of single rubidium atoms trapped in solid neon

David M. Lancaster, Ugne Dargyte, Jonathan D. Weinstein

In this work, we optically resolve and detect individual rubidium atoms trapped in solid neon. Additionally, we optically pump the rubidium's spin state using polarized light and measure the spin state via laser-induced fluorescence. When combined with the previously demonstrated magnetic field sensing capabilities of matrix-isolated rubidium atoms, these results are very promising for nanoscale sensing and for performing nuclear magnetic resonance (NMR) spectroscopy of individual molecules cotrapped in the matrix.
