摘要:

对NV色心在钻石中零磁场下出现的准共振射频场下能级反交叉信号的响应进行了研究。证明该响应的复杂结构可通过Autler-Townes分裂解释。考虑了控制能级反交叉信号参数的可能性。显示在低频外部磁场调制下,该结构中中心共振的斜率可比无射频场时的共振斜率高2.3倍。得出关于零磁场下NV色心中能级反交叉效应本质的结论。

英文摘要:

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.
