Conformal Field Theory Approach to the 2-Impurity Kondo Problem: Comparison with Numerical Renormalization Group Results
Ian Affleck, Andreas W. W. Ludwig, Barbara A. Jones
Numerical renormalization group and conformal field theory work indicate that the two impurity Kondo Hamiltonian has a non-Fermi liquid critical point separating the Kondo-screenin…

Random Worlds and Maximum Entropy
A. J. Grove, J. Y. Halpern, D. Koller
Given a knowledge base KB containing first-order and statistical facts, we consider a principled method, called the random-worlds method, for computing a degree of belief that some…

Collective excitations in double-layer quantum Hall systems
A. H. MacDonald, Shou-Cheng Zhang
We study the collective excitation spectra of double-layer quantum-Hall systems using the single mode approximation. The double-layer in-phase density excitations are similar to th…
