Fig.#cod#x00A0;3. Schematic for the tilted Heisenberg model. In the process of exchange interaction, neighboring spins undergo a relative rotation, which is defined on the bond of the neighbors. For the same spin b 2 , the rotation matrix is different when it interacts with different neighbors a 1 and a 2 . [ 37 ]
