Eigenvalue instantons in the spectral form factor of random matrix model
Abstract We study the late time plateau behavior of the spectral form factor in the Gaussian Unitary Ensemble (GUE) random matrix model. The time derivative of the spectral form factor in the plateau regime is not strictly zero, but non-zero due to a nonperturbative correction in the 1/N expansion....
