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…
