Low temperature expansion of the gonihedric Ising model (1997)
We investigate a model of closed $(d-1)$-dimensional soft-self-avoiding random surfaces on a $d$-dimensional cubic lattice. The energy of a surface configuration is given by $E=J(n_{2}+4k n_{4})$,...
GEOMETRICAL STRING and DUAL SPIN SYSTEMS (1995)
Savvidy, G. K., Savvidy, K. G., Wegner, F. J.
We are able to perform the duality transformation of the spin system which was found before as a lattice realization of the string with linear action. In four and higher dimensions this spin system...
Geometrical String and Spin Systems (1993)
We formulate a new geometrical string on the euclidean lattice. It is possible to find such spin systems with local interaction which reproduce the same surface dynamics.In the three-dimensional case...
