Description
Many materials that behave as so-called non-relativistic
fluids with strong interactions exhibit interesting
properties, such as non-conventional superconductivity and
superfluidity. The fact that non-relativistic fluids do
not necessarily allow for boost symmetries poses a problem
for making predictions using hydrodynamics, in which
normally Lorentz or Galilean boosts are assumed. Me and my
collaborators generalized the framework of hydrodynamics to
work beyond situations where there is a boost symmetry. I
will talk about this framework. As a proof of principle, I
will compute the speed of sound for a gas of Lifshitz
particles, which is a realization of a non-relativistic
fluid without boost symmetry. If time permits I will cover
some beyond ideal fluid results.
