abstract

We present a new formalism for numerically treating the semiclassical gravitational collapse of a scalar quantum field in the radially symmetric case. Our formalism is time reversal invariant and the evolution of the scalar fields is unitary. We present some first results in the angular momentum $l=0$ approximation for an initially coherent state of a massless field and briefly discuss future prospects.

  1. Quantum correlations in a gravitational collapse simulation with SpheriCo.jl

    gr-qc 2024-12 conditional novelty 6.0 of 10

    SpheriCo.jl enables longer semiclassical collapse simulations and yields hints of non-trivial correlations of the scalar field across a dynamically formed apparent horizon.
