Abstract

The infinite-range Sherrington-Kirkpatrick Ising spin-glass model with a transverse field and a random longitudinal field is studied by combining the pair approximation with the discretized path-integral representation. The effects of a transverse field and a random longitudinal field on the instability freezing boundary are examined when random fields are trimodal, and the previous results for the vanishing of the longitudinal field can be recovered.
