Scalar field critical collapse in 2+1 dimensions

Scalar field critical collapse in 2+1 dimensions

We carry out numerical experiments in the critical collapse of a spherically symmetric massless scalar field in 2+1 spacetime dimensions in the presence of a negative cosmological constant and compare them against a new theoretical model. We approximate the true critical solution as the \(n=4\) Garf...

Zusammenfassung:We carry out numerical experiments in the critical collapse of a spherically symmetric massless scalar field in 2+1 spacetime dimensions in the presence of a negative cosmological constant and compare them against a new theoretical model. We approximate the true critical solution as the \(n=4\) Garfinkle solution, matched at the lightcone to a Vaidya-like solution, and corrected to leading order for the effect of \(\Lambda
