Description
Summary:	We revisit quantum criticality of d -dimensional n -vector transverse Ising-like models by means of a conventional one-loop renormalization group (RG) approach with temperature scaling. Focusing on dimensionalities d 3) to I = 2 is found by decreasing the temperature to zero. Besides we provide information about the low-temperature physics within the thermally disordered region usually ignored in the literature. A similar scenario takes place for d = 3 , but now logarithmic corrections to the mean-field power-law behavior are involved.
