【摘要】 构造了激发双模SU(2)相干态|M,ξ;m>=AMξma+mb+m|M,ξ>,并用数值方法研究其非经典特性。结果表明,在双模SU(2)相干态的两场模同时增加光子后,两模光场仍然保持反关联特性,而且可以使光场对Cauchy-Schwartz不等式的破坏程度、光场的反聚束效应以及光子统计亚泊松分布等非经典特性得到加强。更多还原

【Abstract】 The excited double-mode SU(2) coherent state is introduced and its nonclassical properties are investigated with numeric method. The results exhibit that when the photons are added to the fields of the double mode SU(2) coherent state, the two field modes can preserve anti-correlation character. The violation of Cauchy-Schwartz inequality, the sub-Poissonian photon statistics properties and the anti-bunching effect of the fields are all enhanced.更多还原
