论文摘要
研究了水平的抗跨信号对准循环射频场的响应，该频率出现在钻石的NV颜色中心的零磁场中。结果表明，该响应的复杂结构可以通过挤压分裂来解释。考虑控制水平抗跨信号的参数的可能性。结果表明，在外部磁场的低频调制下，在此结构中记录的中央共振的斜率可能是在没有RF场的情况下记录的共振斜率的2.3倍。得出结论是关于钻石NV颜色中心零场的水平抗跨效应的性质。
The response of the level anti-crossing signal to a quasi-resonant radio-frequency field, which appears in a zero magnetic field at NV color centers in diamond, is investigated. It is shown that the complex structure of this response can be explained by the Autler-Townes splitting. The possibility of controlling the parameters of the level anti-crossing signal is considered. It is shown that the slope of the central resonance recorded in this structure upon low-frequency modulation of the external magnetic field can be 2.3 times higher than the slope of the resonance recorded in the absence of an RF field. Conclusions are drawn about the nature of the level anti-crossing effect arising in zero field in NV color centers in diamond.
