Title | Normal charge densities in quantum critical superfluids |
Abstract | I will discuss recent work on the normal charge density in quantum critical superfluids. The work is motivated by recent experiments on overdoped cuprate superconductors which indicate a non-zero density of uncondensed charge carriers at zero temperature. I will show this is consistent with translation invariant two-fluid hydrodynamics and is a consequence of an underlying quantum critical phase. I illustrate this with a holographic model of superfluidity which exhibits similar transport properties. Time permitting, I will discuss expectations for the normal charge density in critical phases with generic critical exponents. |
