abstract
We analyze the stress-energy tensor necessary to generate a general stationary and axisymmetric spacetime. The constraints on the geometry arising from considering a perfect fluid as a source are derived. For a fluid with a nonzero stress tensor, we obtain two necessary conditions on the metric. As an example, we show that the rotating wormhole presented in the literature can not be described by either a perfect fluid or by a fluid with anisotropic stresses.

The authors derive charged rotating Casimir wormhole metrics where thermal stress-energy components are determined to satisfy the Einstein equations, preserving static shape functions for constant ZAMO rotation or damping frame-dragging at large distances.
