Quadratic replica coupling in the Sherrington–Kirkpatrick mean field spin glass model
Quadratic replica coupling in the Sherrington–Kirkpatrick mean field spin glass model
We develop a very simple method to study the high temperature, or equivalently high external field, behavior of the Sherrington–Kirkpatrick mean field spin glass model. The basic idea is to couple two different replicas with a quadratic term, trying to push out the two replica overlap from its replica symmetric …
