Heavy Fermion Emerging from the Singular Fermi Liquid in Underscreened Kondo Model for Eu Compounds

An underscreened Kondo model for the impurity spin S = 7/2 in a weak crystal field is studied to elucidate the Kondo effect in the Eu compounds. By utilizing the numerical renormalization group method, we first confirmed an appearance of the so-called singular Fermi-liquid (SFL) state in the absence...
