CFT in AdS and boundary RG flows
Simone Giombi, Himanshu Khanchandani
Using the fact that flat space with a boundary is related by a Weyl transformation to anti-de Sitter (AdS) space, one may study observables in boundary conformal field theory (BCFT…
Defect Fusion and Casimir Energy in Higher Dimensions
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on phys…
Line Defects in Fermionic CFTs
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study line defects in the fermionic CFTs in the Gross-Neveu-Yukawa universality class in dimensions . These CFTs may be described as the IR fixed points of the Gross-Neve…
RG Interfaces from Double-Trace Deformations
Simone Giombi, Elizabeth Helfenberger, Himanshu Khanchandani
We study a class of interface conformal field theories obtained by taking a large CFT and turning on a relevant double-trace deformation over half space. At low energies, this…
