Emergence and correspondence for string theory black holes

Abstract

This is one of a pair of papers that give a historical-cum-philosophical analysis of the endeavour to understand black hole entropy as a statistical mechanical entropy obtained by counting string-theoretic microstates. Both papers focus on Andrew Strominger and Cumrun Vafa's ground-breaking 1996 calculation, which analysed the black hole in terms of D-branes. The first paper gives a conceptual analysis of the Strominger-Vafa argument, and of several research efforts that it engendered. In this paper, we assess whether the black hole should be considered as emergent from the D-brane system, particularly in light of the role that duality plays in the argument. We further identify uses of the quantum-toclassical correspondence principle in string theory discussions of black holes, and compare these to the heuristics of earlier efforts in theory construction, in particular those of the old quantum theory.

Bardeen black hole in magnetically charged four-dimensional Einstein-Gauss-Bonnet gravity

“…Physicists are always fascinated by Black hole physics and pay attention to it over decades. This is not only because that black hole physics itself is deserved Bardeen black hole in magnetically charged four-dimensional Einstein-Gauss-Bonnet g to be well studied, but also theoretically it has deeply connection to many other different subjects of physics, especially in string theory and AdS/CFT [1][2][3][4][5][6]. Nowadays, we have much better understanding of black holes in practical since the detection of gravitational waves (GWs) of black hole binary mergers [7] by the LIGO and VIRGO observatories and the captured image of the black hole shadow of a supermassive M87 black hole by the Event Horizon Telescope Collaboration [8,9].…”
