abstract
We conducted three torsion-balance experiments to test the gravitational inverse-square law at separations between 9.53 mm and 55 micrometers, probing distances less than the dark-energy length scale $\lambda_{\rm d}=\sqrt[4]{\hbar c/\rho_{\rm d}}\approx 85 \mu$m. We find with 95% confidence that the inverse-square law holds ($|\alpha| \leq 1$) down to a length scale $\lambda = 56 \mu$m and that an extra dimension must have a size $R \leq 44 \mu$m.

Quadratic gravity with Weyl-squared and Ricci-squared terms produces PPN parameters that equal their GR values except for exponentially decaying corrections, with gamma identically 1 when the two mode masses are equal, yielding solar-system lower bounds m_R, m_W greater than or equal to 23 per AU.
Quadratic curvature gravity on Einstein manifolds decouples into massless and non-Fierz-Pauli massive gravity sectors, enabling observational constraints on its parameters with noted tension for the Weyl term.
UV completeness in scalar-tensor gravity restricts the fifth-force Yukawa parameters α and λ to a narrow wedge in parameter space, ruling out its complement and part of the experimentally allowed domain.
Multi-axion theories solving the strong CP problem produce varied mass-coupling relations via a general sum rule that depends on the details of PQ symmetry breaking and anomaly alignments.
Torsion-bar detector with differential mass cancellation reaches |α_Y| = 2.4×10^{-5} at λ = 8 m for Yukawa gravity deviations, limited by source-mass geometry uncertainties after ~26 hours.
Gravitational dark matter candidates with masses in [10^{-3}, 1] eV could produce a measurable effective time variation of the proton mass with future atomic clocks.
Proposes gravitational redshift measurements with atomic clocks in varying density environments to constrain the parameter space of the environment-dependent dilaton model, focusing on regions with weak couplings complementary to existing tests.
Experiments confirm general relativity to high precision in weak-field and strong-field regimes, with gravitational wave damping matching predictions to better than 0.5 percent.
