In the same diagrams we have included the quadratic dispersion relation of the magnons. The heisenberg model, developed by werner heisenberg, is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spins of the magnetic systems are treated quantum mechanically. With two freely tunable constants j1, j2 for the heisenberg model the quantities of interest are in many cases the partition function. While there has been an ongoing debate about the nature of scientific explanation since carl hempel advanced his covering law model in 1948.
