WebSep 20, 2024 · The Ising Model is a mathematical model that doesn't correspond to an actual physical system. It's a huge (square) lattice of sites, where each site can be in one of two states. We label each site with an index , and we call the two states and . To say that the 'th site is in the state , we write . WebThe model can be de ned on any lattice, but for concreteness (and to keep things simple) we will here limit ourselves to a hypercubic lattice in ddimensions (d= 1;2;3).1;2The S iare spin operators which live on the lattice sites.
