From cold Fermi fluids to the hot QGP
Marcus Bluhm, Thomas Schaefer
Strongly coupled quantum fluids are found in different forms, including ultracold Fermi gases or tiny droplets of extremely hot Quark-Gluon Plasma. Although the systems differ in t…
Determination of the density and temperature dependence of the shear viscosity of a unitary Fermi gas based on hydrodynamic flow
Marcus Bluhm, Jiaxun Hou, Thomas Schaefer
We determine the shear viscosity of the ultracold Fermi gas at unitarity in the normal phase using hydrodynamic expansion data. The analysis is based on a generalized fluid dynamic…
Model-independent determination of the shear viscosity of a trapped unitary Fermi gas: Application to high temperature data
Marcus Bluhm, Thomas Schaefer
Determinations of the shear viscosity of trapped ultracold gases suffer from systematic, uncontrolled uncertainties related to the treatment of the dilute part of the gas cloud. In…
Dissipative fluid dynamics for the dilute Fermi gas at unitarity: Anisotropic fluid dynamics
Marcus Bluhm, Thomas Schaefer
We consider the time evolution of a dilute atomic Fermi gas after release from a trapping potential. A common difficulty with using fluid dynamics to study the expansion of the gas…
Medium effects and the shear viscosity of the dilute Fermi gas away from the conformal limit
Marcus Bluhm, Thomas Schaefer
We study the shear viscosity of a dilute Fermi gas as a function of the scattering length in the vicinity of the unitarity limit. The calculation is based on kinetic theory, which…
Dissipative fluid dynamics for the dilute Fermi gas at unitarity: Free expansion and rotation
Thomas Schaefer
We investigate the expansion dynamics of a dilute Fermi gas at unitarity in the context of dissipative fluid dynamics. Our aim is to quantify the effects of shear viscosity on the…
