Shear viscosity of a universal Fermi gas near the superfluid phase transition
J. A. Joseph, E. Elliott, J. E. Thomas
We precisely measure the shear viscosity for a resonantly interacting Fermi gas as a function of temperature, from nearly the ground state through the superfluid phase transition a…
Anomalous minimum in the shear viscosity of a Fermi gas
E. Elliott, J. A. Joseph, J. E. Thomas
We measure the static shear viscosity in a two-component Fermi gas near a broad collisional (Feshbach) resonance, as a function of interaction strength and energy. We find that…
Observation of conformal symmetry breaking and scale invariance in expanding Fermi gases
E. Elliott, J. A. Joseph, J. E. Thomas
We precisely test scale invariance and local thermal equilibrium in the hydrodynamic expansion of a Fermi gas of atoms as a function of interaction strength. After release from an…
Observation of shock waves in a strongly interacting Fermi gas
James Joseph, John E. Thomas, Manas Kulkarni +1
We study collisions between two strongly interacting atomic Fermi gas clouds. We observe exotic nonlinear hydrodynamic behavior, distinguished by the formation of a very sharp and…
Sound propagation in a Fermi gas near a Feshbach resonance
J. Joseph, B. Clancy, L. Luo +3
Sound waves are observed and studied in an optically trapped degenerate Fermi gas of spin-up and spin-down atoms with magnetically tunable interactions. Measurements are made throu…
