Nuclear Physics & RIKEN Theory Seminar

"Perfect Fluids: From Nano to Terra (Kelvin)"

Presented by Thomas Schaefer, North Carolina State University

It has been argued that the quark gluon plasma produced at RHIC is a ``perfect fluid'', i.e. that it saturates a proposed lower bound on the viscosity-to-entropy density ratio. In order to better understand what this means, and to get a feeling for how reliably one can extract the viscosity of a strongly coupled quantum fluid, I have studied the thermodynamic and transport properties of cold trapped fermions. In this talk I will focus, in particualr, on transport in the ``unitarity limit'', that is the limit in which the low energy s-wave cross section between the atoms saturates the quantum mechanical unitarity bound.
