I show that novel Efimov Physics is expected in gravitationally polarizable nonbaryonic dark matter beyond the Standard Model with van der Waals-like forces driven by quantum gravitational fluctuations. I also discuss ground and space-based tests of spacetime curvature effects on weakly bound, highly diffuse quantum three-body systems with standard electrodynamical van der Waals forces. Finally, I consider exotic gravitational quantum matter from higher-order Brunnian structures and analogies with classical systems, already proven in three-stranded DNA, driven by the stochastic gravitational wave background.eninfo:eu-repo/semantics/closedAccessQuantum systems in curved spacetimegravimetryEfimov physicsdispersion forces in curved spacetimeQuantumCasimirForcesArticle10.1142/S02182718184700162-s2.0-85048657237
