An exact spherically symmetric thin shell solution to the Einstein equations is obtained in the Weyl–Dirac theory with an oscillating scalar field. Boundary conditions are chosen such that the conformal invariance is broken in the interior space and the bubble has a scalar‐field‐induced surface stress‐energy tensor that causes the thin shell to oscillate.

Abstract
An exact spherically symmetric thin shell solution to the Einstein equations is obtained in the Weyl–Dirac theory with an oscillating scalar field. Boundary conditions are chosen such that the conformal invariance is broken in the interior space and the bubble has a scalar‐field‐induced surface stress‐energy tensor that causes the thin shell to oscillate.File in questo prodotto:
