Renormalization group and fractal cluster model of spin glasses
M. A. Contínentino, S. Moss de Oliveira
Recent dynamic experiments on spin glasses, in which contours of constant relaxation time are obtained in the plane of magnetic field versus temperature, are discussed from a renormalization-group point of view. We show that two fixed points control the critical behavior of spin glasses and the critical exponents associated with them can be determined through the dynamic experiments. We give a renormalization-group formulation of the fractal cluster model of spin glasses.
