Paper of Masanori Hanada and the Monte Carlo String/M-theory collaboration published in JHEP

The paper “Precision test of gauge/gravity duality in D0-brane matrix model at low temperature“, co-authored by Stratos Pateloudis (Regensburg), Georg Bergner (Jena), Masanori Hanada, Enrico Rinaldi (Michigan and RIKEN, Japan), Andreas Schäfer (Regensburg), Pavlos Vranas (Lawrence Livermore Laboratory), Hiromasa Watanabe (Kyoto), Norbert Bodendorfer (Regensburg), and the Monte Carlo String/M-theory collaboration, has been published in the Journal of High Energy Physics (publisher link here). The main results are in Figures 1 & 2 (shown below). The authors tested the gauge/gravity duality that relates quantum black hole and non-gravitational quantum system in unprecedented precision. The blue line in Figure 1 is the mass of a black hole calculated in the gravity side, by using the Bekenstein-Hawking formula. The points with error bars are the energy of the non-gravitational system. According to the gauge/gravity duality conjecture, they must be the same value at low temperature, modulo a small string-theoretic corrections. The authors see a nice agreement, and the small difference takes the form expected from superstring theory. The paper provides a very strong test of the duality conjecture.
