Modelling of strain effects in manganite films
C. A. Perroni, V. Cataudella, G. De Filippis +3
Thickness dependence and strain effects in films of perovskites are analyzed in the colossal magnetoresistance regime. The calculations are based on a generaliza…
Ground state features of the Frohlich model
G. De Filippis, V. Cataudella, V. Marigliano Ramaglia +2
Following the ideas behind the Feynman approach, a variational wave function is proposed for the Fröhlich model. It is shown that it provides, for any value of the electron-phonon…
Infrared conductivity of a one-dimensional charge-ordered state: quantum lattice effects
C. A. Perroni, V. Cataudella, G. De Filippis +3
The optical properties of the charge-ordering () phase of the one-dimensional (1D) half-filled spinless Holstein model are derived at zero temperature within a well-known varia…
Infrared absorption of the charge-ordering phase: Lattice effects
C. A. Perroni, V. Cataudella, G. De Filippis +3
The phase diagram of the half-filled spinless Holstein model for electrons interacting with quantum phonons is derived in three dimensions extending at finite temperature a var…
