我们开发了一种自旋磁共振的引力模拟，称为自旋引力共振，引力波与磁场相互作用产生自旋跃迁。特别是，外部磁场将自旋 $1/2$ 粒子的能量自旋态分开，并且引力波的存在会对与引力波传播正交的磁场分量产生扰动。在这个框架中，我们测试戴森的猜想，即单个引力子无法被检测到。尽管我们没有发现任何基本定律阻止用自旋引力共振检测单个引力子，但我们表明它不能在实践中使用，支持戴森的猜想。
We develop a gravitational analogue of spin magnetic resonance, called spin gravitational resonance, whereby a gravitational wave interacts with a magnetic field to produce a spin transition. In particular, an external magnetic field separates the energy spin states of a spin-$1/2$ particle, and the presence of the gravitational wave produces a perturbation in the components of the magnetic field orthogonal to the gravitational-wave propagation. In this framework we test Dyson's conjecture that individual gravitons cannot be detected. Although we find no fundamental laws preventing single gravitons being detected with spin gravitational resonance, we show that it cannot be used in practice, in support of Dyson's conjecture.
