We present a theory of the transmission of guided matter-waves through Sagnac interferometers. Interferometer configurations with only one input and one output port have a property similar to the phase rigidity observed in the transmission through Aharonov-Bohm interferometers in coherent mesoscopic electronics. This property enables their operation with incoherent matter-wave sources. High rotation sensitivity is predicted for high finesse configurations.
我们提出了一种关于引导物质波通过萨格纳克干涉仪传输的理论。仅具有一个输入端口和一个输出端口的干涉仪配置具有一种类似于在相干介观电子学中通过阿哈罗诺夫 - 玻姆干涉仪传输时所观察到的相位刚性的特性。这种特性使得它们能够使用非相干物质波源进行操作。对于高精细度配置，预测具有高旋转灵敏度。
