Unconventional metallic conduction in two-dimensional Hubbard-Wigner lattices
S. Fratini, J. Merino
The interplay between long-range and local Coulomb repulsion in strongly interacting electron systems is explored through a two-dimensional Hubbard-Wigner model. An unconventional…
Polaronic signatures in the optical properties of NdCeCuO
E. Cappelluti, S. Ciuchi, S. Fratini
We investigate the temperature and doping dependence of the optical conductivity of NdCeCuO in terms of magnetic/lattice polaron formation. We employ dynamic…
Current saturation and Coulomb interactions in organic single-crystal transistors
S. Fratini, H. Xie, I. N. Hulea +2
Electronic transport through rubrene single-crystal field effect transistors (FETs) is investigated experimentally in the high carrier density regime (n ~ 0.1 carrier/molecule). In…
Electron-phonon and electron-electron interactions in organic field effect transistors
S. Fratini, A. F. Morpurgo, S. Ciuchi
Recent experiments have demonstrated that the performances of organic FETs strongly depend on the dielectric properties of the gate insulator. In particular, it has been shown that…
Polaronic features in the optical properties of the Holstein-t-J model
E. Cappelluti, S. Ciuchi, S. Fratini
We derive the exact solution for the optical conductivity of one hole in the Holstein-t-J model in the framework of dynamical mean-field theory (DMFT). We investigate the ma…
Optical properties of the Holstein-t-J model from dynamical mean-field theory
E. Cappelluti, S. Ciuchi, S. Fratini
We employ dynamical mean-field theory to study the optical conductivity of one hole in the Holstein-t-J model. We provide an exact solution for in the limit of infini…
