Pauli paramagnetism of an ideal Fermi gas
Ye-Ryoung Lee, Tout T. Wang, Timur M. Rvachov +3
We show how to use trapped ultracold atoms to measure the magnetic susceptibility of a two-component Fermi gas. The method is illustrated for a non-interacting gas of Li, using…
Formation of Ultracold Fermionic NaLi Feshbach Molecules
Myoung-Sun Heo, Tout T. Wang, Caleb A. Christensen +5
We describe the formation of fermionic NaLi Feshbach molecules from an ultracold mixture of bosonic 23Na and fermionic 6Li. Precise magnetic field sweeps across a narrow Feshbach r…
Compressibility of an Ultracold Fermi Gas with Repulsive Interactions
Ye-Ryoung Lee, Myoung-Sun Heo, Jae-Hoon Choi +4
Fermi gases with repulsive interactions are characterized by measuring their compressibility as a function of interaction strength. The compressibility is obtained from in-trap den…
Response to comment by Tin-Lun Ho on "Itinerant Ferromagnetism in a Strongly Interacting Fermi Gas of Ultracold Atoms", Science 325, 1521 (2009)
Gyu-Boong Jo, Ye-Ryoung Lee, Jae-Hoon Choi +5
Ho claims in his comment that our experiment is direct evidence that itinerant ferromagnetism does not exist in ultracold Fermi gases. This claim is incorrect and based on an inval…
Itinerant Ferromagnetism in a Fermi Gas of Ultracold Atoms
Gyu-Boong Jo, Ye-Ryoung Lee, Jae-Hoon Choi +5
Can a gas of spin-up and spin-down fermions become ferromagnetic due to repulsive interactions? This question which has not yet found a definitive theoretical answer was addressed…
Matter-wave Interferometry with Phase Fluctuating Bose-Einstein Condensates
G. -B. Jo, J. -H. Choi, C. A. Christensen +4
Elongated Bose-Einstein condensates (BECs) exhibit strong spatial phase fluctuations even well below the BEC transition temperature. We demonstrate that atom interferometers using…
