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 pseudo-orbit correlations in the same way as in [S. Heusler et al. 2007 Phys. Rev. Lett. {\bf 98}, 044103] we find a discrepancy between the semiclassical and the random matrix theory ...
