摘要

从理论上研究了超导人工原子中四波混频对方位和径向涡旋的调制。当两个控制场都带有轨道角动量（OAM）时，可以通过调整两个OAM模式的方位和径向指标来灵活调制FWM场的强度和相位分布。如果只有一个控制场处于两个OAM模式的叠加状态，则叠加OAM可以有效地转移到FWM场。此外，当只有一个控制场处于单一OAM模式时，可以通过调整控制场的失谐和强度来控制FWM场的空间相位。我们提出的方案提供了一种在超导人造原子中实现OAM传输和螺旋相位调节的方法，并可能在微波光学中找到非线性量子应用。

Vortex modulation via four-wave mixing in superconducting artificial atoms

We theoretically study the azimuthal and radial vortex modulation via four-wave mixing (FWM) in superconducting artificial atoms. When both control fields carry orbital angular momentum (OAM), the intensity and phase distribution of the FWM field can be flexibly modulated by adjusting the azimuthal and radial indices of the two OAM modes. If only one control field is in a superposition of two OAM modes, the superposition OAM can be effectively transferred to the FWM field. Additionally, when only one control field is in a single OAM mode, the spatial phase of the FWM field can be manipulated by adjusting the detuning and intensity of the control field. Our proposed scheme provides a way to realize OAM transmission and spiral phase regulation in superconducting artificial atoms, and may find nonlinear quantum applications in microwave optics.
