On The Zero Temperature Critical Point in Heavy Fermions
arXiv:cond-mat/9602145 · doi:10.1007/s002570050200
Abstract
We generalize the scaling theory of heavy fermions for the case the shift exponent describing the critical Neel line is different from the crossover exponent characterizing the coherence line. We obtain the properties of the non-Fermi liquid system at the critical point and in particular the electrical resistivity. We study violation of hyperscaling in the Fermi liquid regime below the coherence line where the properties of heavy fermions are described by mean-field exponents.
