Negative scaling dimensions and conformal invariance at the Nishimori point in the +/-J random-bond Ising model

We reexamine the disorder-dominated multicritical point of the two-dimensional +/-J Ising model, known as the Nishimori point (NP). At the NP we investigate numerically and analytically the behavior of the disorder correlator, familiar from the self-dual description of the pure critical point of the...
