Penumbra diffraction in the quantization of concave billiards
Harel Primack, Holger Schanz, Uzy Smilansky +1
The semiclassical description of billiard spectra is extended to include the diffractive contributions from orbits which are nearly tangent to a concave part of the boundary. The l…
Mixed Quantum-Classical versus Full Quantum Dynamics: Coupled Quasiparticle-Oscillator System
Holger Schanz, Bernd Esser
The relation between the dynamical properties of a coupled quasiparticle-oscillator system in the mixed quantum-classical and fully quantized descriptions is investigated. The syst…
Transfer and Decay of an Exciton Coupled to Vibrations in a Dimer
Holger Schanz, Ivan Barvik, Bernd Esser
Transfer and decay dynamics of an exciton coupled to a polarization vibration in a dimer is investigated in a mixed quantum-classical picture with the exciton decay incorporated by…
Nonadiabatic couplings and incipience of quantum chaos
Holger Schanz, Bernd Esser
The quantization of the electronic two site system interacting with a vibration is considered by using as the integrable reference system the decoupled oscillators resulting from t…
