Coupled-Spin Models  

In General > s.a. path integrals; quantum spin models; spinors in field theory; statistical mechanics.
* Frustration: A situation in the classical theory in which there is little or no long-range ordering between coupled lattice sites in the ground state, e.g., in spin-glass theory with a tetrahedral lattice, there are antiferromagnetic couplings between magnetic spins that cannot be antiparallel.
