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…

Spectral properties and isotope effect in strongly interacting systems: Mott-Hubbard insulator and polaronic semiconductor

S. Fratini, S. Ciuchi

We study the electronic spectral properties in two examples of strongly interacting systems: a Mott-Hubbard insulator with additional electron-boson interactions, and a polaronic s…

Pairing and polarization in systems with retarded interactions

S. Ciuchi, G. Sangiovanni, M. Capone

In a system where a boson (e.g, a phonon) of finite frequency is coupled to electrons, two phenomena occur as the coupling is increased: electron pairing and polarization of…

Pressure dependence of superconducting and magnetic critical temperatures in the ruthenocuprates

R. Citro, G. G. N. Angilella, M. Marinaro +1

We study the dependence on filling and pressure of the superconducting and ferromagnetic critical temperatures of the ruthenocuprates, within the two-band model. At zero pressure,…

Quantum Heisenberg antiferromagnets: a survey of the activity in Firenze

Umberto Balucani, Luca Capriotti, Alessandro Cuccoli +5

Over the years the research group in Firenze has produced a number of theoretical results concerning the statistical mechanics of quantum antiferromagnetic models, which range from…
