Replica solution of the random energy model
Abstract
The alternative replica technique which involves summation over all integer momenta of the partition function and which does not require analytic continuation to noninteger values of the replica parameter n is discussed. In terms of this technique (which does not involve any replica symmetry breaking "magic operations"), a wellknown solution for the average free energy of the random energy model is recovered in a very simple way.
