(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

hamiltonian is given by H=-[tex]\sum [/tex] J_{ij}s_{i}s_{j}

so interaction constants are J_{ij}=E_{i}E_{j}and Ei=+1,-1

s_{i}=+1,-1 randomly , they are spin variables.

the question is :

show that this system is equivalent to a ferromagnet, by redefining the spin variables.

3. The attempt at a solution

first of all i am not sure but J_{ij}should be less than zero. If i know the definiton of ferromagnetic system , i can change the spin variables into an appropriate form. but far now i couldn't find anyhing

So any tip or lead would be nice to start with.

thanks
