| Abstract | Physical Review A, Rapid Communications, 89, 020701(R) (2014) We report the observation of resonance-like loss in the trap population of
ultracold dysprosium as a function of magnetic field, which we attribute to
anisotropy-induced Fano-Feshbach resonances arising from Dy's large magnetic
dipole moment and nonzero electronic orbital angular momentum. We recorded
these resonances for four different isotopes, three bosonic and one fermionic,
over a field range of 0-6 G and show that the number of resonances changes
significantly as a function of temperature, even in the nK regime. Most of the
observed resonances are of very narrow width. The fermionic isotope, unlike its
bosonic counterparts, possesses nonzero nuclear spin and exhibits a much higher
density of resonances. |
