Quantum Creation of Black Hole by Tunneling in Scalar Field Collapse

TL;DR

This paper explores how quantum tunneling can induce black hole formation in scalar field collapse scenarios where classical physics predicts no black hole creation.

Contribution

It introduces a quantum tunneling mechanism in scalar field collapse, extending classical solutions to include quantum effects leading to black hole formation.

Findings

Quantum tunneling enables black hole formation in subcritical collapse.

Self-similar solutions are used to analyze quantum effects.

Results suggest quantum effects can alter classical collapse outcomes.

Abstract

Continuously self-similar solution of spherically symmetric gravitational collapse of a scalar field is studied to investigate quantum mechanical black hole formation by tunneling in the subcritical case where, classically, the collapse does not produce a black hole.
