SUMMARY

The discussion focuses on calculating the lengths of closed orbits in Hamiltonian systems using the Gutzwiller formula. The Hamiltonian is defined as H = p² + V(x), where the challenge lies in determining the lengths of closed orbits for various Hamiltonian systems beyond simple cases like the harmonic oscillator. The Gutzwiller formula requires a summation over these lengths to compute the density of states g(E), emphasizing the importance of classical periodic orbits in this semi-classical approach.

PREREQUISITES
  • Understanding of Hamiltonian mechanics
  • Familiarity with the Gutzwiller formula

given a Hamiltonian H=p^2 + V(x) how can you calculate the length of the closed orbits ? , i mean in gutzwiller formula you must perform a summation over the length of the closed orbits to calculate density of states g(E) but how can you know what the lenghts are ?? .. of course for Harmonic Oscillator orbits are circles so we can calculate their length but how about for other Hamiltonian systems ?

The Gutzwiller formula is semi-classical. It uses classical periodic orbits.
