Non-Relativistic Scale Anomalies

Understand

We extend the cohomological analysis in arXiv:1410.5831 of anisotropic Lifshitz scale anomalies.

• We consider non-relativistic theories with a dynamical critical exponent $z=2$ with or without non-relativistic boosts and a particle number symmetry.
• We distinguish between cases depending on whether the time direction does or does not induce a foliation structure.
• We analyse both $1+1$ and $2+1$ spacetime dimensions.
