A random surface theory with non-trivial γ string
Abstract
We measure by Monte Carlo simulations γ string for a model of random surfaces embedded in three dimensional Euclidean space-time. The action of the string is the usual Polyakov action plus an extrinsic curvature term. The system undergoes a phase transition at a finite value βc of the extrinsic curvature coupling and at the transition point the numerically measured value of γstring ( λc) ≈ 0.27 ± 0.06. This is consistent with γ string (λ c) = {1}/{4}, i.e. equal to the first of the non-trivial values of γ string between 0 and {1}/{2}.
