Surprises in the Ordinary: $O (N)$ Invariant Surface Defect in the $ε$ -expansion

Oleksandr Diatlyk, Zimo Sun, Yifan Wang

We study an $O (N)$ invariant surface defect in the Wilson-Fisher conformal field theory (CFT) in $d = 4 - ε$ dimensions. This defect is defined by mass deformation on a two-dimensional…

Effective Field Theory of Conformal Boundaries

Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1

We introduce an effective field theory (EFT) for conformal impurity by considering a pair of transversely displaced impurities and integrating out modes with mass inversely proport…

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…
