"Quantum Spectra of Triangular Billiards on the Sphere"

J. Phys. A: Math. Theor. 34(12) (2001) 2549
We study the quantal energy spectrum of triangular billiards on a spherical surface. Group theory yields analytical results for tiling billiards while the generic case is treated numerically. We find that the statistical properties of the spectra do not follow the standard random matrix results and their peculiar behaviour can be related to the corresponding classical phase space structure.
