Quantum criticality in the spin-isotropic pseudogap Bose-Fermi Kondo model: Entropy, scaling, and the -theorem

Z Yu, F Zamani, P Ribeiro, S Kirchner - Physical Review B, 2020 - APS
We study the behavior of the entropy of the pseudogap Bose-Fermi Kondo model within a
dynamical large-N limit, where N is related to the symmetry group of the model. This model …
