Anti--de Sitter/ boundary conformal field theory correspondence in the non-relativistic limit [PDF]
Eur. Phys. J. C (2012) 72:2115 DOI 10.1140/epjc/s10052-012-2115-x, 2012 Boundary conformal field theory (BCFT) is the study of conformal field theory (CFT) in semi-infinite space-time. In non-relativistic limit ($x\rightarrow\epsilon x, t\rightarrow t, \epsilon\rightarrow 0$), boundary conformal algebra changes to boundary Galilean conformal algebra (BGCA).

Boundary conformal field theory and a boundary central charge [PDF]
Journal of High Energy Physics, 2017 We consider the structure of current and stress tensor two-point functions in conformal field theory with a boundary. The main result of this paper is a relation between a boundary central charge and the coefficient of a displacement operator correlation

Superconformal models for graphene and boundary central charges
Journal of High Energy Physics, 2018 In the context of boundary conformal field theory, we investigate whether the boundary trace anomaly can depend on marginal directions in the presence of supersymmetry. Recently, it was found that a graphene-like non-supersymmetric conformal field theory

Calculation of Four Point Correlation Function of Logarithmic Conformal Field Theory Using AdS/CFT Correspondence [PDF]
Phys.Lett. B548 (2002) 237-242, 2002 We use the correspondence between scalar field theory on AdS and induced conformal field theory on its boundary to calculate correlation functions of logarithmic conformal field theory in arbitrary dimensions.Our calculations utilize the newly proposed method of nilpotent weights.We derive expressions for the four point function assuming a generic ...

Boundary holographic Witten diagrams
Journal of High Energy Physics, 2017 In this paper we discuss geodesic Witten diagrams in generic holographic conformal field theories with boundary or defect. Boundary CFTs allow two different de-compositions of two-point functions into conformal blocks: boundary channel and ambient ...

Defect scaling Lee–Yang model from the perturbed DCFT point of view
Nuclear Physics B, 2014 We analyze the defect scaling Lee–Yang model from the perturbed defect conformal field theory (DCFT) point of view. First the defect Lee–Yang model is solved by calculating its structure constants from the sewing relations.

Boundary states in c=−2 logarithmic conformal field theory [PDF]
Nucl.Phys. B639 (2002) 450-470, 2002 Starting from first principles, a constructive method is presented to obtain boundary states in conformal field theory. It is demonstrated that this method is well suited to compute the boundary states of logarithmic conformal field theories. By studying the logarithmic conformal field theory with central charge c=-2 in detail, we show that our method ...

Scale invariance vs. conformal invariance: holographic two-point functions in Horndeski gravity
European Physical Journal C: Particles and Fields, 2019 We consider Einstein-Horndeski gravity with a negative bare constant as a holographic model to investigate whether a scale invariant quantum field theory can exist without the full conformal invariance.
