摘要：

New studies of the T=0 scaling theory of Gaussian and bimodal spin glasses, based on exact transfer matrix calculations and on Migdal-Kadanoff scaling, are performed. The authors focus on the area and length dependencies of the energy sensitivity to changes in the boundary conditions and on the role of vacancies in the bimodal model. They calculate the fractal dimensionality of domain walls in the 2D bimodal systems, valid for short length scales.
