Transition of a small-bipolaron gas to a Frohlich polaron in a deformable lattice

The electronic properties of guest Cs atoms in a deformable lattice are investigated at various densities n. Low values of n show optical absorptions of small bipolarons. At intermediate n values, new bands appear in the midinfrared (MIR) and high-frequency regions, which coexist with the small bipo...
