论文摘要
我们在许多核自旋的极限中获得了中央旋转框模型中核自旋动力学的非线性方程的紧凑分析溶液。沿外部磁场的总核自旋成分是保守的，并且根据电子自旋极化的不同，这两个垂直成分螺旋成分先图或振荡，频率由核自旋极化确定。作为解决方案的应用，我们计算核自旋噪声谱并描述在没有系统激发的情况下核自旋挤压和许多身体纠缠的影响。
We obtain a compact analytical solution for the nonlinear equation for the nuclear spin dynamics in the central spin box model in the limit of many nuclear spins. The total nuclear spin component along the external magnetic field is conserved and the two perpendicular components precess or oscillate depending on the electron spin polarization, with the frequency, determined by the nuclear spin polarization. As applications of our solution, we calculate the nuclear spin noise spectrum and describe the effects of nuclear spin squeezing and many body entanglement in the absence of a system excitation.
