Fig. 5: Excluding parameter values using data from Holometer and QUEST.
From: Signatures of correlation of spacetime fluctuations in laser interferometers
Excluded region in the parameter space of ΓS and \(\kappa={\ell }_{r}/{{{\mathcal{L}}}}\) for correlation classes: (a) factorised ρF, (b) inverse ρIm, and (c) exponential ρEm, where m = S (m = ST) denotes correlations depending on spatial (spacetime) separation. Data from the Holometer excludes the regions shaded in blue and red; data from QUEST excludes the blue region only. The black dashed (ΓSκ2 ⩽ 6.173 × 10−32), dot-dashed (ΓSκ2 ⩽ 1.25 × 10−35), dotted (ΓSκ2 ⩽ 1.234 × 10−32), and dot-dot-dashed (ΓSκ2 ⩽ 2.812 × 10−36) lines denote curves fitted to the boundary of the excluded regions.
