Abstract

We consider the energy-averaged two-point correlator of spectral determinants and calculate contributions beyond the diagonal approximation using semiclassical methods. Evaluating the contributions originating from pseudoorbit correlations in the same way as in Heusler et al (2007 Phys. Rev. Lett. 98 044103) we find a discrepancy between the semiclassical and the random matrix theory result. A ...
