The paper “Bulk geometry in gauge/gravity duality and color degrees of freedom“, with sole author Masanori Hanada, has been published this week (6 May 2021) by Physical Review D (link here). The paper contains a breakthrough in gauge/gravity duality. Historically, gauge/gravity duality claims superstring theory is equivalent to certain non-gravitational quantum theories. Although there is ample evidence supporting this duality, questions such as — how is the geometry in superstring theory encoded in non-gravitational theories? — have remained open. After the discovery of gauge/gravity duality in 1997, there was a promising scenario based on the matrix degrees of freedom. However, in 1998, a “no-go” argument was made, and people gave up on this scenario. Then, surprisingly, twenty-three years later, Masanori found a fatal flaw in the no-go argument. The details of how the no-go argument is falsified are given in this paper. The image below show Figure 1 from the paper.
