Semiclassical Non-Trace Type Formulas for Matrix Element Fluctuations and Weighted Densities of States
J. Main, G. Wunner
Densities of states weighted with the diagonal matrix elements of two operators A and B, i.e., rho^(A,B)(E) = sum_n <n|A|n><n|B|n> delta(E-E_n) cannot, in general, be written as a…

Semiclassical Spectra and Diagonal Matrix Elements by Harmonic Inversion of Cross-Correlated Periodic Orbit Sums
J. Main, K. Weibert, V. A. Mandelshtam +1
Semiclassical spectra weighted with products of diagonal matrix elements of operators A_{alpha}, i.e., g_{alpha alpha'}(E) = sum_n <n|A_{alpha}|n><n|A_{alpha'}|n>/(E-E_n) are obtai…

Uniform semiclassical approximations for umbilic bifurcation catastrophes
J. Main, G. Wunner
Gutzwiller's trace formula for the semiclassical density of states diverges at the bifurcation points of periodic orbits and has to be replaced with uniform semiclassical approxima…
