DESCRIPTION:Mark Alford\, Washington University in St. Louis\n\nThe hydrody
namic description of a superfluid at non-zero temperature is the two-fluid
model\, where the two fluids are the superfluid and a normal fluid. The s
uperfluid is a Bose-Einstein condensate\, and the normal fluid is a therma
l gas of phonons.
\n
\nI will show how one can translate between the
macroscopic two-fluid model and a microscopic field theoretic description
\, using the simplest field theory that can show Bose-Einstein condensatio
n\, namely the complex scalar field.
\n
\nQuestions that will be ans
wered include:\n
* How can one get two fluids from a single field?
\n* What is the relationship between the different formalisms that have be
en proposed for relativistic superfluids?\n* What is the role of the
Goldstone boson?
