The Gonihedric Ising model originates from catching basic properties of fluctuating random surfaces in a bosonic string theory. Formulated as a lattice model of interacting classical spins it can be investigated by means of the multicanonical Monte Carlo algorithm to resolve open questions on the first order phase transition. The transition temperature has been determined for the model and a dual representation; also the interface tension has been measured for both models and appears to be quite strong. |
