Strings in charge-transfer Mott insulators: effects of lattice vibrations and the Coulomb interaction
Applying the canonical transformation with the 1/\lambda perturbation expansion in the nonadiabatic and intermediate regime and the discrete generalisation of Pekar's continuous nonlinear equation in the extreme adiabatic regime we show that there are no strings in narrow-band ionic insulators...
