Euclidean Correlation Functions in a Holographic Model of QCD
Thomas Schaefer
We compute euclidean coordinate space correlation functions in a holographic model of QCD. We concentrate, in particular, on channels that are related to the U(1)_A problem, the fl…
Color superconductivity in dense quark matter
Mark G. Alford, Krishna Rajagopal, Thomas Schaefer +1
Matter at high density and low temperature is expected to be a color superconductor, which is a degenerate Fermi gas of quarks with a condensate of Cooper pairs near the Fermi surf…
Shear viscosity of a superfluid Fermi gas in the unitarity limit
Gautam Rupak, Thomas Schaefer
We compute the shear viscosity of a superfluid atomic Fermi gas in the unitarity limit. The unitarity limit is characterized by a divergent scattering length between the atoms, and…
Perfect Fluidity in Atomic Physics
Thomas Schaefer
Experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) have been interpreted in terms of a strongly interacting quark gluon plasma. The strongly interacting pl…
What atomic liquids can teach us about quark liquids
Thomas Schaefer
We discuss some aspects of cold atomic Fermi gases in the unitarity limit that are of interest in connection with the physics of quark matter and the quark gluon plasma. We conside…
Bulk viscosity due to kaons in color-flavor-locked quark matter
Mark G. Alford, Matt Braby, Sanjay Reddy +1
We calculate the bulk viscosity of color-superconducting quark matter in the color-flavor-locked (CFL) phase. We assume that the lightest bosons are the superfluid mode H and the k…
The Shear Viscosity to Entropy Density Ratio of Trapped Fermions in the Unitarity Limit
Thomas Schaefer
We extract the shear viscosity to entropy density ratio η/s of cold fermionic atoms in the unitarity limit from experimental data on the damping of collective excitations. We find…
