Using the replica method they can solve the model exactly, allowing explicitly for replica symmetry breaking. The solution is replica symmetric and marginally stable. However, perturbations around the spherical model, in particular the introduction of an on-site Ising-like spin length probability, destabilise the replica symmetric solution and give rise to a new solution. The mass of the fluctuations destroying replica symmetry is shown to depend on the fourth cumulant of the spin length distribution for a given site.Read More
