Conformal field theories in a periodic chemical potential

Co-authors: Andrew Lucas (Harvard University), Paul Chesler (Harvard University)

We compare field-theoretic and holographic results on the structure of 2+1 dimensional conformal field theories placed in a periodic chemical potential with amplitude V and wavevector k. General arguments are presented that the infrared limit is described by an emergent conformal field theory whose universality class changes at an infinite discrete set of values of V/k. Electrical transport properties are computed: the holographic method captures some, but not all, of the expected structure.
