An Exact No-Rotation Criterion in Circular Stationary Spacetimes
Abstract
We derive an exact no-rotation criterion for circular, stationary, axisymmetric spacetimes from Einstein's field equations. Its integrated form excludes frame dragging when the weighted matter contribution is nonpositive, the boundary flux vanishes, and the bulk integrals converge. For opposing momentum sources, a finite-region argument excludes frame dragging in a regular region when its boundary values tend uniformly to zero. Time-independent minimally coupled canonical real scalars illustrate the opposing sign, whereas harmonic complex fields can supply angular momentum. In the Barriola--Vilenkin scalar model, the application covers global helical fields with general meridional amplitudes, including possible higher-winding monopole configurations. A persistent vacuum field at an asymptotically conical end locks the phase pattern to the asymptotic frame, excluding horizonless rotation. A nonzero transverse horizon amplitude also synchronizes the horizon with that frame and makes the exterior nonrotating.
