Rashba effect in quantum networks
Dario Bercioux, Michele Governale, Vittorio Cataudella +1
We present a formalism to study quantum networks made up by single-channel quantum wires in the presence of Rashba spin-orbit coupling and magnetic field. In particular, linear tra…
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…
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…
Rashba effect induced localization in quantum networks
Dario Bercioux, Michele Governale, Vittorio Cataudella +1
We study a quantum network extending in one-dimension (chain of square loops connected at one vertex) made up of quantum wires with Rashba spin-orbit coupling. We show that the Ras…
