Rotating wormholes with a varying conical deficit: source structure and scalar mode conversion

We study a rotating traversable wormhole with an $l$-dependent conical factor, where the conical deficit is localized near the throat and vanishes in both asymptotic regions. For radial null directions we obtain \[ 8πG\,T_{μν}k^μk^ν= -2\frac{r''}{r} -\frac{α''}α -2\frac{r'α'}{rα} + \frac{N'}{N} \lef
