| Description: | [DPS Seminar] Sridip Pal (University of California) -- Weyl (Conformal/Scale) Anomalies in Non-Relativistic Quantum Field Theory |
| Date: | Wednesday, Dec 21, 2016 |
| Time: | 2 p.m. - 3 p.m. |
| Venue: | G02, Lecture Hall Complex |
| Details: | Weyl consistency conditions have been used in unitary relativistic quantum field theory to impose constraints on the renormalization group (RG) flow of certain quantities. We classify the Weyl anomalies and their renormalization scheme ambiguities for generic non-relativistic theories in 2+1 dimensions with anisotropic scaling exponent z=2; the extension to other values of z are discussed as well. We give the consistency conditions among these anomalies. As an application we find several candidates for a C-theorem. We comment on possible candidates for a C-theorem in higher dimensions. I will also make some generic remarks about non-relativistic CFTs, coupling them conformally with curved background. I will also provide example of Lagrangian theory where z flows under RG. |
