Abstract:
We present numerical evidence that the techniques of conformal field theory might be applicable to two-dimensional Ising spin glasses with Gaussian bond distributions. It is shown that certain domain wall distributions in one geometry can be related to that in a second geometry by a conformal transformation. We also present direct evidence that the domain walls are stochastic Loewner (SLE) processes with kappa approximate to 2.1. An argument is given that their fractal dimension d(f) is related to their interface energy exponent theta by d(f)-1=3/[4(3+theta)], which is consistent with the commonly quoted values d(f)approximate to 1.27 and theta approximate to-0.28.
