偶极场对阱中粒子的几何相位诱导假电偶极矩信号的贡献

Dipole-Field Contributions to Geometric-Phase-Induced False Electric-Dipole Moment Signals for Particles in Traps

P. G. Harris, J. M. Pendlebury

摘要:

在较早的出版物中已经表明,施加到阱中的粒子的磁场梯度可以引起拉莫尔频率偏移,该频率偏移可能被错误地解释为电偶极矩(EDM)信号。这项研究现在已经扩展到包括不均匀的磁场梯度,由于存在一个本地的磁偶极子。据发现,在高轨道频率制度,可以提高超出简单的期望的体积平均磁场梯度成比例的位移的幅度。

英文摘要:

It has been shown in an earlier publication that magnetic field gradients applied to particles in traps can induce Larmor frequency shifts that may falsely be interpreted as electric-dipole moment (EDM) signals. This study has now been extended to include nonuniform magnetic field gradients due to the presence of a local magnetic dipole. It is found that, in the high orbit-frequency regime, the magnitude of the shifts can be enhanced beyond the simple expectation of proportionality to the volume-averaged magnetic-field gradient.
