Description
We use the Hamiltonian version of the semiclassical Einstein equation to study gravity coupled to a real scalar field. Starting from the full Einstein-Klein-Gordon system, we restrict to the spherically symmetric sector and derive the phase space equations of motion. In the semiclassical regime, we could do away with the scalar field equations and replace the scalar field variables by their expectations, which, in turn, could be viewed as free functions of the radial coordinate. This allows us to numerically find various static geometries, such as Boson stars, worm holes, and black holes. Our results are significant as they incorporate full backreaction of quantum matter on classical gravity.
