THE 2-DIMENSIONAL HARMONIC-OSCILLATOR INTERACTING WITH A WEDGE

The exact propagator of our dynamic system is presented and confirmed by expanding it in terms of the energy eigenfunctions and eigenvalues, which agree with those obtained from the corresponding Schrodinger equation. For the case of a rational wedge the propagator can be expressed as a sum over `classical paths', but with the modified Van-Vleck formula. We also evaluate the density matrix and the partition function.
