Description
Carrollian symmetries arise when the speed of light is taken to zero. I will describe how Carrollian fluids sponaneously break boost symmetries, which provides a unifying description that ties together several seemingly disparate notions of Carrollian fluids that have appeared previously. The associated Goldstone mode allows us to construct an effective Aristotelian geometry, implying that previous results about Aristotelian fluids can be used to describe the first-order hydrodynamics. Furthermore, this effective Aristotelian structure gives rise to a Horava-Lifshitz-like effective action for the Goldstone.
