Holography, Duality and Higher-Spin Theories
A. C. Petkou
I review recent work on the holographic relation between higher-spin theories in Anti-de Sitter spaces and conformal field theories. I present the main results of studies concernin…
Lee-Yang edge singularity in the three-dimensional Gross-Neveu model at finite temperature
A. C. Petkou, G. Siopsis
We discuss the relevance of the Lee-Yang edge singularity to the finite-temperature Z_2-symmetry restoration transition of the Gross-Neveu model in three dimensions. We present an…
Aspects of the conformal operator product expansion in AdS/CFT correspondence
L. Hoffmann, A. C. Petkou, W. Ruehl
We present a detailed analysis of a scalar conformal four-point function obtained from AdS/CFT correspondence. We study the scalar exchange graphs in AdS and discuss their analytic…
Finite-Size and Finite-Temperature Effects in the Conformally Invariant O(N) Vector Model for 2<d<4
Anastasios C. Petkou, Nicholas D. Vlachos
We study the operator product expansion (OPE) of the auxiliary scalar field λ(x) with itself, in the conformally invariant O(N) Vector Model for 2<d<4, to leading order in 1/N in a…
