Description
Conformal field theories are relativistic quantum field theories with conformal symmetry. Defect CFTs have point or line or planar defects that further reduce the conformal symmetry to that of the defect. When the bulk is free and massless — a free massless scalar or fermion or photon — there are strong constraints on the conformal data that raise hope of achieving a partial or total classification of these theories. Moreover, some may have relevance for graphene, carbon nanotubes, and other experimental systems. We will survey recent results about these systems, including work in progress on free in the bulk fermions.
