报告摘要：I will be giving a detailed analysis of Galilean (non-relativistic) versions of conformal field theories. I will show that in all these cases, the field theories exhibit Galilean conformal structures in appropriate dimensions. Unlike relativistic conformal invariance, the surprising aspect of the analysis is that the non-relativistic conformal structure becomes infinite-dimensional even when looking at spacetime dimensions greater than two.

In every case, if the parent relativistic theory exhibited conformal invariance, we find an infinitely enhanced Galilean conformal invariance in the non-relativistic case. This leads to suggest that the enhancement of symmetries in the non-relativistic limit is a generic feature of conformal field theories in any dimension.

报告人简介：I am currently a Junior Scientist/Postdoc at the Max Planck Institute for Gravitational Physics (AEI), working under the supervision of Prof. Stefan Theisen since December 2019. I did my PhD from IIT Kanpur, India under Dr Arjun Bagchi.
