We have new results on spectroscopy of thulium atoms implanted in solid argon and neon. This atom has it’s outer electronic shells “closed” – the active electrons are in the “submerged” 4f shell. This leads to unusually narrow optical spectra on the magnetic dipole transition at 1140 nm: we see lines as narrow as 500…

We have a new publication from our shaking lattice experiment, published in Physical Review A. In this work we put a molecular BEC of lithium atom pairs into a shaking optical lattice. The shaking lattice gives the atoms and effective negative mass, and the creates an instability. Surprisingly, we find that this instability results in…

In a new paper published in Physical Review Letters, we have developed and deployed a novel method to determine the spin susceptibility of ultracold Fermi gases. These gases are created by cooling lithium atoms to less than 1 millionth of a degree Kelvin – a temperature low enough that the dilute gas of atoms takes…
