Abstract
A nonconventional renormalization group procedure, which involves fixed poi nts and eigenvectors depending on temperature T, is proposed to describe cl assical-quantum crossover phenomena for quantum systems near criticality. I n this new picture, T-dependent critical exponents occur, where T assumes t he role of a natural crossover parameter. (C) 2001 Elsevier Science B.V. Al l rights reserved.
