摘　　要：围绕临界现象研究了原子系综的耦合动力学特性,研究发现在一定条件下无自旋交换驰豫(SERF)惯性测量系统会表现出SERF磁场测量特性;在不同频率横向磁场激励下,系综耦合动力学特性会呈现出由SERF惯性测量特性到SERF磁场测量特性的演化。研究结果表明:通过增大收敛频率可以优化惯性测量的灵敏度和带宽。The coupled dynamics of atomic ensemble are researched based on the critical phenomenon,and it's revealed that under certain conditions,the spin exchange relaxation free(SERF)comagnetometer will exhibit magnetic field measurement characteristics as a SERF magnetometer.Under the excitation of transverse magnetic fields with different frequencies,the coupled dynamics will exhibit an evolution of characteristics from a SERF comagnetometer to a SERF magnetometer.The results indicate that increasing the convergence frequency can optimize the sensitivity and bandwidth of the comagnetometer.
