Logrithmic corrections to the RG flow for the two-dimensional bond disordered Ising model
Erik S. Sorensen
Using the mapping of the partition function of the two-dimensional Ising model onto a pfaffian we evaluate the domain wall free energy difference for the pure and disordered Ising…

Interaction between impurities and solitons in quasi one-dimensional spin-Peierls systems
D. Augier, P. Hansen, D. Poilblanc +2
The role of the spin-phonon coupling in spin-Peierls chains doped with spin-0 or spin-1 impurities is investigated by various numerical methods such as exact diagonalization, quant…

Is there an exponentially large Kondo screening cloud ?
Erik Sorensen, Ian Affleck
We make a precise scaling conjecture, based on renormalization group ideas, regarding the screening cloud around an impurity spin in the Kondo effect and test it numerically using…
