| 14:00 - 15:00 Weekly Seminar HEPCo Group Aspects of boundary conformal field theories School PHYSICS Abstract: I will talk about the boundary invariants in the case of the 3,4 and 5 dimensional boundary conformal field theories and will discuss how one could derive the conformal anomaly in the presence of the boundary. I will also discuss entanglement entropy and the holographic prescription for these cases. Date: Tuesday, August 31 2 p.m (Tehran time) Zoom.

I will show how this notion is motivated from holography and discuss its generic properties. I will report numerical studies of this quantity in free scalar theories and in spin systems and show that this quantity can be regarded as a new quantum order parameter. |
