Query: Crossover from Anderson- to Kondo-like behavior: Universality induced by
  spin-charge separation   The thermodynamics of a lattice regularized asymmetric Anderson impurity in a
correlated host is obtained by an exact solution. The crossover from the
Anderson- to the Kondo-regime is studied, thus making contact with predictions
by scaling theory. On the basis of the exact solution, the transition to
universal Kondo behavior is shown to be realized by a graduate separation of
the energy scales of spin and charge excitations.
