用相干态研究Sp(4)模型的基态相变
The Ground State Phase Transition of the Sp(4) Model Via the Coherent State Methodology
【摘要】 本文利用相干态,通过求算子的微分表示方法,研究了同时考虑单极力和单极对力的Sp(4)模型的基态相变,提取了该模型的序参量,给出了与精确解相比误差小于5%的基态能量。
【Abstract】 In this paper, the ground state phase transition of the Sp(4) model which includes monopoly interaction and monopole pairing interaction is studied by using coherent state methodology via the differential representation of the operators. The order parameter of the model is extracted, and the ground state energy whose errors are less 5% than the exact solution.
