Optical Conductivity of the Holstein Polaron [PDF]

open access: yesPhysical Review Letters, 2011
The Momentum Average approximation is used to derive a new kind of non-perturbational analytical expression for the optical conductivity (OC) of a Holstein polaron at zero temperature. This provides insight into the shape of the OC, by linking it to the structure of the polaron's phonon cloud.
