Conformal field theories in a periodic potential: Results from holography and field theory
We study (2+1)-dimensional conformal field theories (CFTs) with a globally conserved U(1) charge, placed in a chemical potential which is periodically modulated along the spatial direction x with zero average: μ(x)=V cos(kx). The dynamics of such theories depends only on the dimensionless ratio V/k,...
