Critical dynamics from statics

Using the mapping of d-dimensional time-dependent Ginzburg-Landau models in d dimensions onto associated (d+1)-dimensional static systems, we calculate the dynamic critical exponents in terms of static ones by using the Feynman graph expansion of critical exponents. Moreover, the dynamic-scaling hypothesis is traced back to anisotropic scaling in the associated (d+1)-dimensional model, yielding new exponent equalities. © 1985 The American Physical Society.
