Specific Heat of the Kondo Model
Abstract
The magnetic impurity contribution to the specific heat of metals is calculated as a function of temperature. The calculation, based on the solution of a recently proposed spinless model for the Kondo problem, shows the specific heat as a universal function of the temperature scaled by the Kondo temperature. The universal function is well described by the analytically solvable resonant-level model over the entire temperature range.
