Metastability in Spin-Polarized Fermi Gases
Y. A. Liao, M. Revelle, T. Paprotta +4
We study the role of particle transport and evaporation on the phase separation of an ultracold, spin-polarized atomic Fermi gas. We show that the previously observed deformation o…
Spin-Imbalance in a One-Dimensional Fermi Gas
Yean-an Liao, Ann Sophie C. Rittner, Tobias Paprotta +5
Superconductivity and magnetism generally do not coexist. Changing the relative number of up and down spin electrons disrupts the basic mechanism of superconductivity, where atoms…
Absence of Pressure-Driven Supersolid Flow at Low Frequency
Ann Sophie C. Rittner, Wonsuk Choi, Erich J. Mueller +1
An important unresolved question in supersolid research is the degree to which the non-classical rotational inertia (NCRI) phenomenon observed in the torsional oscillator experimen…
Probing the Upper Limit of Nonclassical Rotational Inertia
Ann Sophie C. Rittner, John D. Reppy
We study the effect of confinement on solid 4-He's nonclassical rotational inertia (NCRI) in a torsional oscillator by constraining it to narrow annular cells of various widths. Th…
Annealing in solid He
Ann Sophie C. Rittner, John D. Reppy
We have used a torsional oscillator with square cross section and a resonance frequency of 185 Hz to confirm the nonclassical rotational inertia (NCRI) discovered by Kim and Chan\c…
Disorder and the Supersolid State of Solid He
Ann Sophie C. Rittner, John D. Reppy
We report torsional oscillator supersolid studies of highly disordered samples of solid He. In an attempt to approach the amorphous or glassy state of the solid, we prepare our…
