Anisotropic collisions of dipolar Bose-Einstein condensates in the universal regime
Nathaniel Q. Burdick, Andrew G. Sykes, Yijun Tang +1
We report the measurement of collisions between two Bose-Einstein condensates with strong dipolar interactions. The collision velocity is significantly larger than the internal vel…
Anisotropic expansion of a thermal dipolar Bose gas
Yijun Tang, Andrew G. Sykes, Nathaniel Q. Burdick +3
We report on the anisotropic expansion of ultracold bosonic dysprosium gases at temperatures above quantum degeneracy and develop a quantitative theory to describe this behavior. T…
A long-lived spin-orbit-coupled degenerate dipolar Fermi gas
Nathaniel Q. Burdick, Yijun Tang, Benjamin L. Lev
We describe the creation of a long-lived spin-orbit-coupled gas of quantum degenerate atoms using the most magnetic fermionic element, dysprosium. Spin-orbit-coupling arises from a…
Bose-Einstein condensation of 162Dy and 160Dy
Yijun Tang, Nathaniel Q. Burdick, Kristian Baumann +1
We report Bose-Einstein condensation of two isotopes of the highly magnetic element dysprosium: 162Dy and 160Dy. For 162Dy, condensates with 10^5 atoms form below T = 50 nK. We fin…
Fermionic suppression of dipolar relaxation: Observation of universal inelastic dipolar scattering
Nathaniel Q. Burdick, Kristian Baumann, Yijun Tang +2
We observe the suppression of inelastic dipolar scattering in ultracold Fermi gases of the highly magnetic atom dysprosium: the more energy that is released, the less frequently th…
Observation of low-field Fano-Feshbach resonances in ultracold gases of dysprosium
Kristian Baumann, Nathaniel Q. Burdick, Mingwu Lu +1
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-Feshb…
Quantum degenerate dipolar Fermi gas
Mingwu Lu, Nathaniel Q. Burdick, Benjamin L. Lev
The interplay between crystallinity and superfluidity is of great fundamental and technological interest in condensed matter settings. In particular, electronic quantum liquid crys…
A Strongly Dipolar Bose-Einstein Condensate of Dysprosium
Mingwu Lu, Nathaniel Q. Burdick, Seo Ho Youn +1
We report the Bose-Einstein condensation (BEC) of the most magnetic atom, dysprosium. The Dy BEC is the first for an open f-shell lanthanide (rare-earth) element and is produced vi…
