The $O (N)$ model with $ϕ^{6}$ potential in $R^{2} \times R^{+}$

Christopher P. Herzog, Nozomu Kobayashi

We study the large $N$ limit of $O (N)$ scalar field theory with classically marginal $ϕ^{6}$ interaction in three dimensions in the presence of a planar boundary. This theory has an…

Regge OPE blocks and light-ray operators

Nozomu Kobayashi, Tatsuma Nishioka, Yoshitaka Okuyama

We consider the structure of the operator product expansion (OPE) in conformal field theory by employing the OPE block formalism. The OPE block acted on the vacuum is promoted to a…

The gravity dual of Lorentzian OPE blocks

Heng-Yu Chen, Lung-Chuan Chen, Nozomu Kobayashi +1

We consider the operator product expansion (OPE) structure of scalar primary operators in a generic Lorentzian CFT and its dual description in a gravitational theory with one extra…

Towards a $C$ -theorem in defect CFT

Nozomu Kobayashi, Tatsuma Nishioka, Yoshiki Sato +1

We explore a $C$ -theorem in defect conformal field theories (DCFTs) that unify all the known conjectures and theorems until now. We examine as a candidate $C$ -function the addition…

Spinning conformal defects

Nozomu Kobayashi, Tatsuma Nishioka

We consider conformal defects with spins under the rotation group acting on the transverse directions. They are described in the embedding space formalism in a similar manner to sp…
