【摘要】 采用泛函积分方法研究了 Ｄｉｃｋｅ 模型中的临界温度和能隙方程， 计算了模型中的零温度能隙；此外， 还推导了 Ｄｉｃｋｅ 模型中的玻色型激发谱， 讨论了准子粒子的能量和光子振动频率的依赖关系。更多还原

【Abstract】 The critical temperature and energy gap equations in the Dicke model are studied by means of functional integrals method. The zero temperature gap is also calculated; Morever, the bose spectrum is derived in the Dicke model. The relation between quasiparticle energy and photos frequency is discussed.更多还原
