论文摘要
使用费米框架的构造，可以用引力 - 电磁磁场横向向传播方向和彼此正交的引力 - 电磁场来描述。特别是，引力磁场作用于旋转颗粒，我们表明，由于重力波场的作用，我们称之为引力 - 磁性共振的新现象。我们给出了这种现象的经典和量子描述，并建议它可以用作新型引力波检测器的基础。我们的结果突出了集体旋转激发的有效性，例如在检测高频重力波中，磁化材料中的自旋波。在这里，我们建议，当重力波诱导电子自旋的动力时，功率将以具有磁化球体的四极对称性的铁磁谐振模式释放。这为检测引力波的重力磁效应提供了可能的途径。
Using the construction of the Fermi frame, the field of a gravitational wave can be described in terms of gravito-electromagnetic fields that are transverse to the propagation direction and orthogonal to each other. In particular, the gravito-magnetic field acts on spinning particles and we show that, due to the action of the gravitational wave field, a new phenomenon, that we call gravito-magnetic resonance, may appear. We give both a classical and a quantum description of this phenomenon and suggest that it can be used as the basis for a new type of gravitational wave detectors. Our results highlight the effectiveness of collective spin excitations, e.g. spin waves in magnetized materials, in detecting high frequency gravitational waves. Here we suggest that, when gravitational waves induce a precession of the electron spin, power is released in the ferromagnetic resonant mode endowed with quadrupole symmetry of a magnetized sphere. This offers a possible path to the detection of the gravito-magnetic effects of a gravitational wave.
