Cosmic Problems for Condensed Matter Experiment
Tanmay Vachaspati
TL;DR
This paper explores how condensed matter systems, like sonic black holes in fluids, can serve as laboratory analogs to test cosmological theories such as Hawking radiation, including recent experimental efforts.
Contribution
It introduces the concept of sonic analogs of black holes and discusses recent experimental proposals and results in condensed matter systems for testing cosmological phenomena.
Findings
Proposal for creating dumbholes in laboratory settings
Discussion of an experiment on Helium-3 AB system
Potential to test Hawking radiation in condensed matter
Abstract
Condensed matter analogs of the cosmological environment have raised the hope that laboratory experiments can be done to test theoretical ideas in cosmology. I will describe Unruh's sonic analog of a black hole (``dumbhole'') that can be used to test Hawking radiation, and some recent proposals on how one might be able to create a dumbhole in the lab. In this context, I also discuss an experiment already done on the Helium-3 AB system by the Lancaster group.
