Effects of the electron-phonon coupling near and within the insulating Mott phase
C. A. Perroni, V. Cataudella, G. De Filippis +1
The role of the electron-phonon interaction in the Holstein-Hubbard model is investigated in the metallic phase close to the Mott transition and in the insulating Mott phase. The m…
Formation of polaron clusters
C. A. Perroni, G. Iadonisi, V. K. Mukhomorov
The formation of spherical polaron clusters is studied within the Frhlich polaron theory. In a dilute polaron gas, using the non-local statistical approach and the polaro…
Effects of electron-phonon coupling range on the polaron formation
C. A. Perroni, V. Cataudella, G. De Filippis +1
The polaron features due to electron-phonon interactions with different coupling ranges are investigated by adopting a variational approach. The ground-state energy, the spectral w…
Transport properties in manganite thin films
S. Mercone, C. A. Perroni, V. Cataudella +10
The resistivity of thin films () is investigated in a wide temperature range. The comparison of the resistivities is made among films grown by di…
Spin polarization of electrons with Rashba double-refraction
V. Marigliano Ramaglia, D. Bercioux, V. Cataudella +2
We demonstrate how the Rashba spin-orbit coupling in semiconductor heterostructures can produce and control a spin-polarized current without ferromagnetic leads. Key idea is to use…
Electron Double Refraction in Hybrid Systems with Rashba Spin-Orbit Coupling
V. Marigliano Ramaglia, V. Cataudella, G. De Filippis +2
We study the scattering of an electron in a definite state of spin at an interface of an hybrid system with a Rashba spin-orbit coupling on one side. Out of the normal incidence th…
