摘要

利用适当探测器框架的形式，研究了引力波与自旋1/2粒子组成的量子二能级系统之间的相互作用。这种方法强调了引力波对粒子和观测者的影响，强调只能进行相对测量。具体地说，在这个框架内，引力波的引力场是用重力电磁类比来描述的。系统的相互作用由引力波的重力磁场决定，引力磁场引起随时间变化的扰动。我们分析了一般频率和共振条件下的这种扰动，并讨论了它的含义。

Quantum two-level systems and gravitational waves

We study the interaction between gravitational waves and a quantum two-level system consisting of a spin 1/2 particle using the formalism of the proper detector frame. This approach highlights the effects of gravitational waves on both the particles and the observer, emphasizing that only relative measurements can be made. Specifically, within this framework, the gravitational field of the waves is described using the gravitoelectromagnetic analogy. The interaction of the system is then determined by the gravitomagnetic field of the wave, which induces a time-dependent perturbation. We analyze this perturbation for both generic frequencies and resonance conditions, and discuss its implications.
