Hopping dynamics of interacting polarons
S. Ciuchi, S. Fratini
We derive an effective cluster model to address the transport properties of mutually interacting small polarons. We propose a decoupling scheme where the hopping dynamics of any gi…
Signatures of polaronic charge ordering in optical and dc conductivity using dynamical mean field theory
S. Ciuchi, S. Fratini
We apply dynamical mean field theory to study a prototypical model that describes charge ordering in the presence of both electron-lattice interactions and intersite electrostatic…
Substrate limited electron dynamics in graphene
S. Fratini, F. Guinea
We study the effects of polarizable substrates such as SiO2 and SiC on the carrier dynamics in graphene. We find that the quasiparticle spectrum acquires a finite broadening due to…
Optical properties of small polarons from dynamical mean-field theory
S. Fratini, S. Ciuchi
The optical properties of polarons are studied in the framework of the Holstein model by applying the dynamical mean-field theory. This approach allows to enlighten important quant…
