摘要:

我们提出了一种用于探测频率在0.3 Hz至5 Hz之间引力波的地面探测器。为此,我们讨论了一种具有单回路和折叠式三回路几何结构的对称物质波干涉仪。后者消除了其他原子干涉探测器中Sagnac效应所要求的飞开尔文能量原子系综的需要。它还结合了当前垂直和水平物质波天线的若干优势,并增强了可扩展性,以实现2·10^-21/√Hz的峰值应变灵敏度。

英文摘要:

We propose a terrestrial detector for gravitational waves with frequencies between 0.3 Hz and 5 Hz. Therefore, we discuss a symmetric matter-wave interferometer with a single loop and a folded triple-loop geometry. The latter eliminates the need for atomic ensembles at femtokelvin energies imposed by the Sagnac effect in other atom interferometric detectors. It also combines several advantages of current vertical and horizontal matter wave antennas and enhances the scalability in order to achieve a peak strain sensitivity of $2\cdot10^{-21}\,/\sqrt{\mathrm{Hz}}$.
