In this talk\, I will explain the notion of anisotropic gravitational W eyl anomalies in Lifshitz field theories and their potential applications. Anomalies are quantum violations of classical symmetries\, in this case u nder a non-relativistic (non-Lorentz-invariant) symmetry group. More speci fically\, I will focus on the only anomaly found in 1+1-dimensional Lifshi tz field theories that arise after coupling to Newton-Cartan geometry with torsion\, and it'\;s relation to the Lorentz (diffeomorphism) anomaly in the quantum effective action of a 1+1 CFT. At the heart of this discuss ion\, I will emphasize the role of temporal torsion in generating this ano maly and show how such an anomaly can be derived from a 2+1-dimensional We yl-invariant Chern-Simons Horava-Lifshitz theory of gravity. I will finall y comment briefly on how the 1+1 Lifshitz Weyl anomaly can potentially be connected to thermal Hall transport and some other potential applications.
