Abstract:
We study the behavior of the fully connected Ising spin glass in a transverse field Γ at T = 0 by exact diagonalization techniques. We find that the order parameter grows linearly with Γc - Γ below Γc. The exact diagonalization method shows a rather good scaling behavior to the large system limit. © 2002 Published by Elsevier Science B.V.
