Dephasing and inhibition of spin interference from semi-classical self-gravitation
摘要：
我们提出了一个详细的推导模型来研究半经典引力的自引力效应，薛定谔-牛顿方程描述，采用自旋叠加态在非均匀磁场中，最近提出的实验寻找引力诱导纠缠。近似实验相关的限制进行了讨论。结果表明，自旋干涉测量可以提供一个更容易的路线走向实验测试的量子方面的重力比以前的建议，以测试半经典引力和引力自旋纠缠的观察。
英文摘要：
We present a detailed derivation of a model to study effects of self-gravitation from semi-classical gravity, described by the Schrödinger-Newton equation, employing spin superposition states in inhomogeneous magnetic fields, as proposed recently for experiments searching for gravity induced entanglement. Approximations for the experimentally relevant limits are discussed. Results suggest that spin interferometry could provide a more accessible route towards an experimental test of quantum aspects of gravity than both previous proposals to test semi-classical gravity and the observation of gravitational spin entanglement.
