Critical behavior of four-dimensional Ising spin glasses with bimodal disorder

We perform Monte Carlo simulations of the bimodal Ising spin-glass model
in four space dimensions. Whereas the critical behavior of the
four-dimensional Ising spin glass with Gaussian disorder has been
studied extensively, the four-dimensional counterpart with bimodal
disorder remains to be studied in detail. Using various observables
such as the Binder cumulant and the spin-glass correlation length, we
perform finite size analysis in order to reexamine the critical
parameters of this model and discuss universality.
