E. Caurier et al., LOGARITHMIC TERMS IN THE SPECTRAL STATISTICS OF BAND RANDOM MATRICES, Journal of physics. A, mathematical and general, 26(15), 1993, pp. 3845-3852
We present a detailed analysis of the nearest-neighbour spacing distri
bution (NNSD) for random matrices on which the non-zero elements are c
onfined to a band around the diagonal. The vanishing of the remaining
elements induces non-analytic (logarithmic) behaviour for the NNSD at
very small spacings. A conjecture for the precise behaviour of these l
ogarithmic terms is presented and supported by extensive numerical com
putations.
