Resonance- and Chaos-Assisted Tunneling
Peter Schlagheck, Christopher Eltschka, Denis Ullmo
We consider dynamical tunneling between two symmetry-related regular islands that are separated in phase space by a chaotic sea. Such tunneling processes are dominantly governed by…

Fermi Edge Singularities in the Mesoscopic Regime: I. Anderson Orthogonality Catastrophe
Martina Hentschel, Denis Ullmo, Harold U. Baranger
For generic mesoscopic systems like quantum dots or nanoparticles, we study the Anderson orthogonality catastrophe (AOC) and Fermi edge singularities in photoabsorption spectra in…
