DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SISSAHEP/1/"
 >Graphene and boundary conformal field theory</a>\nby Christopher Herzog (
 King's College London) as part of SISSA HEP seminars\n\n\nAbstract\nThe in
 frared fixed point of graphene under the renormalization group flow is a r
 elatively under studied yet important example of a boundary conformal fiel
 d theory with a number of remarkable properties. It has a close relationsh
 ip with three dimensional QED. It maps to itself\nunder electric-magnetic 
 duality. Moreover\, it along with its supersymmetric cousins all possess a
 n exactly marginal coupling -- the charge of the electron. I will review p
 ast work on this model and also discuss my own contributions which have fo
 cused on understanding the boundary contributions to the anomalous trace o
 f the stress tensor and their role in helping to understand the structure 
 of boundary conformal field theory. I will also present some results on th
 e hemisphere partition function for supergraphene\, its duality properties
 \, and an exact computation of the conductivity at arbitrary values of the
  interaction strength.\n
