摘要:
一个磁悬浮质量块与引力耦合,可充当有效的引力波探测器。我们证明,在四极磁场中悬浮的超导球受到引力波激发时,会产生磁场涨落,并可使用磁通可调微波谐振器读出。当读出装置工作在标准量子极限时,该系统在1 kHz至1 MHz频率范围内可实现 h ≲ 10^-20/√Hz 的宽带应变噪声灵敏度,为探索新物理的天体物理研究开辟新途径。
英文摘要:
A magnetically levitated mass couples to gravity and can act as an effective gravitational wave detector. We show that a superconducting sphere levitated in a quadrupolar magnetic field, when excited by a gravitational wave, will produce magnetic field fluctuations that can be read out using a flux tunable microwave resonator. With a readout operating at the standard quantum limit, such a system could achieve broadband strain noise sensitivity of $h \lesssim 10^{-20}/\sqrt{\rm Hz}$ for frequencies of $1~\mathrm{kHz}~-~1~\mathrm{MHz}$, opening new corridors for astrophysical probes of new physics.
