Double-Scaled SYK, QCD, and the Flat Space Limit of de Sitter Space
Double-Scaled SYK, QCD, and the Flat Space Limit of de Sitter Space
A surprising connection exists between double-scaled SYK at infinite temperature, and large N QCD. The large N expansions of the two theories have the same form; the 't Hooft limit of QCD parallels the fixed p limit of SYK (for a theory with p-fermion interactions), and the limit of fixed …
