Derivation of the two Schwarzians effective action for the Sachdev–Ye-Kitaev spectral form factor
Abstract The Sachdev–Ye-Kitaev model spectral form factor exhibits absence of information loss, in the form of a ramp and a plateau that are typical in random matrix theory. In a large N collective fields description, the ramp was reproduced by Saad et al. (A semiclassical ramp in SYK and in gravity...
