Lattice polaron formation: Effects of non-screened electron-phonon interaction
H. Fehske, J. Loos, G. Wellein
We explore the quasiparticle properties of lattice polarons on the basis of a quite general electron-phonon Hamiltonian with a long-range displacement-type of interaction. To treat…

Quantum lattice fluctuations in a frustrated Heisenberg spin-Peierls chain
A. Weisse, G. Wellein, H. Fehske
As a simple model for spin-Peierls systems we study a frustrated Heisenberg chain coupled to optical phonons. In view of the anorganic spin-Peierls compound CuGeO3 we consider two…
