Random Surfaces with Ising Spins
In Probabilistic methods in quantum field theory and quantum gravity, eds. P.H. Damgaard, H. Hüffel and A. Rosenblum (Plenum Press, N.Y. 1990), 325-329
Bosonic strings can be discretized in terms of dynamically triangulated random surfaces. We investigate the possibility of introducing fermionic degrees of freedom on the surface in terms of Ising spins, which in two dimensions correspond to Majorana fermions. Critical properties of the model are estimated using finite-size scaling methods.
