T. Banks, W. Fischler, I.R. Klebanov
TL;DR
This paper models Schwarzschild black holes within Matrix theory, describing their formation, stability, and Hawking radiation emission, and compares the theoretical Hawking rate with semiclassical predictions.
Contribution
It introduces a Matrix theory model for Schwarzschild black holes and estimates their Hawking radiation rate, aligning it with semiclassical results.
Findings
Hawking rate matches semiclassical predictions within an order of magnitude.
Black holes are modeled as metastable bound states of D0-branes.
Hawking radiation occurs via emission of small D0-brane clusters.
Abstract
Recently, in collaboration with Susskind, we proposed a model of Schwarzschild black holes in Matrix theory. A large Schwarzschild black hole is described by a metastable bound state of a large number of D0-branes which are held together by a background, whose structure has so far been understood only in 8 and 11 dimensions. The Hawking radiation proceeds by emission of small clusters of D0-branes. We estimate the Hawking rate in the Matrix theory model of Schwarzschild black holes and find agreement with the semiclassical rate up to an undetermined numerical coefficient of order 1.
