Extremal Black Hole and Flux Vacua Attractors
S. Bellucci, S. Ferrara, R. Kallosh +1
These lectures provide a pedagogical, introductory review of the so-called Attractor Mechanism (AM) at work in two different 4-dimensional frameworks: extremal black holes in N=2 s…
Superfield Formulation of Nonlinear N=4 Supermultiplets
S. Bellucci, S. Krivonos, O. Lechtenfeld +1
We propose a unified superfield formulation of N=4 off-shell supermultiplets in one spacetime dimension using the standard N=4 superspace. The main idea of our approach is a "gluin…
N=8 supersymmetric mechanics on the sphere S^3
S. Bellucci, S. Krivonos, A. Sutulin
Starting from quaternionic N=8 supersymmetric mechanics we perform a reduction over a bosonic radial variable, ending up with a nonlinear off-shell supermultiplet with three bosoni…
Filtering of spin currents based on ballistic ring
S. Bellucci, P. Onorato
Quantum interference effects in rings provide suitable means for controlling spin at mesoscopic scales. Here we apply such a control mechanism to the spin-dependent transport in a…
Spin separation in a T ballistic nanojunction due to lateral-confinement-induced spin-orbit-coupling
S. Bellucci, F. Carillo, P. Onorato
We propose a new scheme of spin filtering employing ballistic nanostructures in two dimensional electron gases (2DEGs). The proposal is essentially based on the spin-orbit (SO) int…
Quantum Hall effect in carbon nanotubes and curved graphene strips
E. Perfetto, J. Gonzalez, F. Guinea +2
We develop a long wavelength approximation in order to describe the low-energy states of carbon nanotubes in a transverse magnetic field. We show that, in the limit where the squar…
