1. Numerical Renormalization-group Computation of Specific Heats. / Calor específico do modelo de Anderson de uma impureza por grupo de renormalização numérico
The specific heat and the entropy of the one-impurity symmetric Anderson Model are calculated using the Numerical Renormalization Group (NRG). The heart of the method is the logarithmic discretization of the metal conduction band where the impurity is coupled. However, this discretization, inherent in the method, introduces oscillations in the thermodynamica
