Gauging nonrelativistic symmetries and applications

For quite some time it has been known that nonrelativistic systems possess a bigger symmetry than the usual Galilean symmetry This is the nonrelativistic general coordinate invariance which has found applications in fractional quantum Hall effect FQHE Horava Lifshitz gravity Newton Cartan geometry to name a few In this colloquium we shall introduce a new approach of studying this general coordinate invariance As applications we will show how spatial diffeomorphism symmetry which is relevant for FQHE appears Also a simple realisation of Newton Cartan geometry will be provided that is the basis of Newton s gravity Refreshments are served at 14:45
