Bachelor project description

  1. Read through the derivation Gutzwiller trace formula.
  2. learn the basic equations of elastodynamics
  3. apply the method to
    1. derivation of trace formulas for acoustics
    2. computation of resonance spectra of quartz and aluminium blocks studied experimentally at CATS.
  4. compute the resonance spectrum by some ``traditional'' method

The goal of the project is to confront the theory with measurements that can be performed by our experimentailsts.

  3. The project would take the Niels Søndergaard's speciale Periodic orbit theory applied to acoustics, available at http://www.nbi.dk/~nsonderg/speciale/thesis.html as a starting point.
