Description
Gravitational physics and condensed matter theory provide good motivation to investigate strongly coupled quantum theories in the presence of chemical potentials and curved background geometries. We study systems in 2+1 dimensions consisting of a defect that sources an electric charge, or a magnetic flux, of a U(1) field. We find the effects induced by these defects on quantum conformal fields. Perhaps more intriguingly, we can also hide the defects inside the horizon of a black hole, where they will still have an effect on the quantum conformal fields outside.
