A complete quantum solution provides all possible knowledge of a system, whereas semiclassical theory provides at best approximate solutions in a limited region. Nevertheless, semiclassical methods based on the work of Martin Gutzwiller can provide stunning physical insights in regimes where quantum solutions are opaque. Furthermore, they can provide a unique bridge between the quantum and classical worlds. We illustrate these ideas with an account of a theoretical and experimental attack on… Expand
The theory of the Double Solution: Dynamical issues in quantum systems in the semiclassical regime
The "dynamical mismatch" observed in quantum systems in the semiclassical regime challenge the Pilot wave model. Indeed the dynamics and properties of such systems depend on the trajectories of theExpand

It is found that periodic orbit repetitions are described by "hybrid" orbits, combining both diffractive and geometric core scatters, and that by including all possible permutations the authors can obtain excellent agreement between the semiclassical model and accurate fully quantal calculations.

Recurrence spectroscopy: Observation and interpretation of large-scale structure in the absorption spectra of atoms in magnetic fields.
Bifurcation theory provides organizing principles for understanding this proliferation and for interpreting the data, which interpret as ``recurrence strength,'' as a function of the classical action of the closed orbit. Expand
