Spin-Boson Hamiltonian and Optical Absorption of Molecular Dimers
Christiane Koch, Bernd Esser
An analysis of the eigenstates of a symmetry-broken spin-boson Hamiltonian is performed by computing Bloch and Husimi projections. The eigenstate analysis is combined with the calc…
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…
Excitonic - vibronic coupled dimers: A dynamic approach
Bernd Esser, Holger Schanz
The dynamical properties of exciton transfer coupled to polarization vibrations in a two site system are investigated in detail. A fixed point analysis of the full system of Bloch…
Nonlinearity and trapping in excitation transfer: Dimers and Trimers.
Ivan Barvik, Bernd Esser, Holger Schanz
We study the interplay between nonlinearity in exciton transport and trapping due to a sink site for the dimer and the trimer with chain configuration by a numerical integration of…
