Ordering wavevector
WebIf the magnetic ordering wavevector is non-integer, the dispersion is calculated using a coordinate system rotating from unit cell to unit cell. In this case the spin Hamiltonian has to fulfill this extra rotational symmetry which is not checked programatically. Some of the code of the function can run faster if mex files are used. WebThe ordering wavevector is in A and B and in C and D. The black arrows in Fig. 2B are approximately the ordering wavevectors. (E) The energy gap of CDW produced by the equal amplitude superposition of the charge density wave depicted in A–D. The phase of the superposition is taken to be +, +, −, −, and hence corresponds to a d-wave symmetry.
