SUMMARY:Non-Relativistic Scale Anomalies and Geometry - Igal Arav
DTSTART:20161027T120000Z

DESCRIPTION:I will discuss the coupling of non-relativistic field theories
  to curved spacetime\, and develop a framework for analyzing the possible 
 structure of non-relativistic (Lifshitz) scale anomalies using a cohomolog
 ical formulation of the Wess-Zumino consistency condition. I will compare 
 between cases with or without Galilean boost symmetry\, and between cases 
 with or without an equal time foliation of spacetime. In 2+1 dimensions wi
 th a dynamical critical exponent of z=2\, the absence of a foliation struc
 ture allows for an A-type anomaly in the Galilean case\, but also introduc
 es the possibility of an infinite set of B-type anomalies.\nI will also de
 rive Ward identities for flat space correlation functions in Lifshitz fiel
 d theories\, and develop a method for calculating Lifshitz anomaly coeffic
 ients from these correlation functions using split dimensional regularizat
 ion.\n
