Detailed Description

This class is describes the exchange operator.

The demagnetized energy is \( E= - \frac{1}{\lambda^2} \displaystyle \sum_{i,j=0}^{i,j=P-1} J_{ij} \mu_i \mu_j \)

In order to have \(\displaystyle \forall i \in [0,P[, \frac{dE}{d\mu_i}(P)=-H(P) \),

the corresponding magnetic excitation field is: \( H(P_i)= \frac{2}{\lambda^2} \displaystyle \sum_{j=0}^{j=P-1} J_{ij} \mu_j \)

As H is linear with respect of \( `mu_i\), the energy can also be computed as \( \displaystyle E= - \frac{1}{2} \sum_{i=0}^{P-1} <H(P_i),\mu(P_i)> \)
