AI总结:

该研究以Wigner-Yanase斜信息为量化指标,分析反杰恩斯-卡明斯哈密顿量下二能级原子与单模压缩相干光耦合的原子非经典性动力学,发现参数变化下斜信息演化均呈混合态取值,与压缩效应一致。

摘要:

我们将Wigner-Yanase斜信息作为原子非经典性的量子信息量化指标,用于研究反杰恩斯-卡明斯(AJC)哈密顿量产生的动力学过程,该过程中初始处于原子基态的二能级原子与单模压缩相干光耦合。我们探究了压缩参数、光场强度和耦合强度参数的变化对Wigner-Yanase斜信息动力学的影响。我们观察到,在压缩参数、光场强度和耦合强度参数的所有变化下,Wigner-Yanase斜信息的时间演化均呈现混合态取值,这与压缩效应相符。

英文摘要:

We apply the Wigner-Yanase skew information, as a quantum information quantifier of atomic non-classicality in the dynamics generated by the anti-Jaynes-Cummings (AJC) Hamiltonian when a two-level atom in an initial atomic ground state, couples to a single mode of squeezed coherent light. We investigate the effect of variation of squeeze parameter, field intensity, and coupling strength parameter, on the dynamics of the Wigner-Yanase skew information. We observe that time-evolution of the Wigner-Yanase skew information records mixed state values for all variations of squeeze parameter, field intensity and coupling strength parameter, congruent with squeezing effects.
