Quantum bose and Fermi gases of dysprosium : production and initial study
Abstract/Contents
- Abstract
- Advancements in quantum manipulation of ultracold atomic gases are opening a new frontier in the quest to better understand strongly correlated matter. By exploiting the long-ranged and anisotropic character of the dipole-dipole interaction in ultracold gases, we hope to simulate or create novel forms of quantum matter. Quantum dilute gases of the most magnetic element, dysprosium, provide an important platform to study this dipolar physics. We present details of experiments that produce strongly dipolar Bose-Einstein condensates of Dy164 and Dy162, as well as the first dipolar degenerate Fermi gas of Dy161 (0.2 x Fermi temperature) in low magnetic field. Particularly, we demonstrated for the first time the direct evaporative cooling of single component ultracold fermions (Dy161) to Fermi degeneracy, predicted by universal dipolar scattering theory. Due to its large spin multiplicity in the ground state, large effective gauge fields for simulating, e.g., the quantum Hall effect, may be synthesized by exploiting the Dy atomic structure. Moreover, as a non-S-state atom, Dy is predicted to be an ideal candidate for spin-orbit coupling experiments in ultracold gases since the Raman dressing would be largely free from the incoherent scattering problems induced by the additional laser beams.
