Heisenberg Model and Ising Model

when we talk about magnetism, we use Ising Model or Heisenberg model

if possible can you give me some suggestion about these two model for (one dimensional, two dimensional)

Multiple interacting three-dimensional flaws in electromagnetothermoelastic coupled multiphase composites by extended hypersing

This work presents extended hypersingular integral equation (E-HIE) method to analyze the multiple interacting three-dimensional mixed-mode flaws problem in electromagnetothermoelastic coupled multiphase composites (EMTE-CMCs) under extended electro-magneto-thermo-elastic coupled loads through intricate theoretical analysis and numerical simulations. Using the Green’s functions,  the multiple interacting three-dimensional flaws problem are reduced to solving a set of E-HIEs coupled with extended boundary integral equations, in which the unknown functions are the extended displacement discontinuities.
