Airy distribution of the quenched spectral form factor in non-interacting fermions

For chaotic many-body systems as well as the random energy model, the logarithm of the (scaled) spectral form factor (SFF) exhibits two robust properties at late times: (i) self-averaging and (ii) a reflected-Gumbel distribution. Here, we demonstrate that both properties break down for $N$ non-interacting fermions on a...
