The application of the mean-field theory of Schwinger bosons to the spiral spin systems
碩士 === 國立臺灣大學 === 物理研究所 === 100 === We have analyzed the quantum Heisenberg model on the two and three dimensional Bravais lattice in the spiral spin state using the Schwinger boson mean-field theory. By diagonalizing the system’s Hamiltonian, we obtain the general form of the mean-field free energy...
