On the scaling spectrum of the Anderson impurity model

Abstract:

We consider the universal scaling behaviour of the Kondo resonance in the strong-coupling limit of the symmetric Anderson impurity model, using a recently developed local moment approach. The resultant scaling spectrum is obtained in closed form, and is dominated by long tails that in contrast to previous work are found to exhibit a slow logarithmic decay rather than a power-law form, crossing over to characteristic Fermi liquid behaviour on the lowest energy scales. The resultant theory, whi...
