The spin-double refraction in two-dimensional electron gas
D. Bercioux, V. Marigliano Ramaglia
We briefly review the phenomenon of the spin-double refraction that originates at an interface separating a two-dimensional electron gas with Rashba spin-orbit coupling from a one…
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…
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…
