Complex Periodic Orbits and Tunneling in Chaotic Potentials
Complex Periodic Orbits and Tunneling in Chaotic Potentials
We derive a trace formula for the splitting-weighted density of states suitable for chaotic potentials with isolated symmetric wells. This formula is based on complex orbits which tunnel through classically forbidden barriers. The theory is applicable whenever the tunneling is dominated by isolated orbits, a situation which applies to chaotic …
