摘要：

We investigate the stability of the replica-symmetric solution of the Sherrington-Kirkpatrick(SK)-Ising spin glass in a transverse field. It is shown that the replica-symmetric solution is unstable in the whole lowtemperature phase. The low temperature behaviour is investigated by applying the first stage of replicasymmetry breaking to the present model. © 1990.
