We study the distribution of non-overlapping spacing ratios of higher-ordersfor complex interacting many-body quantum systems, with and without spin degreeof freedom (in addition to the particle number). The Hamiltonian of suchsystems is well represented by embedded one- plus two-body random matrixensembles (with and without spin degree of freedom) for fermionic as well asbosonic systems. We obtain a very good correspondence between the numericalresults and a recently proposed generalized Wigner surmise like scalingrelation. These results confirm that the proposed scaling relation is universalin understanding spacing ratios in complex many-body quantum systems. Usingspin ensembles, we demonstrate that the higher order spacing ratiodistributions can also reveal quantitative information about the underlyingsymmetry structure.
