String Tension Scaling in Gonihedric 3D Ising Models
M Baig , D Espriu, D Johnston and R Malmini
Abstract
For a class of Ising models defined by Savvidy and Wegner the
bare string tension is zero and the energy of a spin interface
depends only on the number of bends and self-intersections, in
antithesis to the standard 3D ising action. In this paper we investigate
the scaling of the renormalized string tension, which is entirely
generated by fluctuations, using Monte-carlo simulations.
The scaling of the string tension allows us to obtains estimates
of the critical exponents alpha and nu using both finite-size scaling
and data collapse techniques.
