The critical properties of the d-dimensional transverse Ising model in the influence domain of its quantum critical point are studied solving the one-loop renormalization group equations around and at d = 3. Different critical regimes occur involving crossover behaviours which can be described in terms of effective exponents, consistently with the conventional crossover theory.

Abstract
The critical properties of the d-dimensional transverse Ising model in the influence domain of its quantum critical point are studied solving the one-loop renormalization group equations around and at d = 3. Different critical regimes occur involving crossover behaviours which can be described in terms of effective exponents, consistently with the conventional crossover theory.File in questo prodotto:
