Infinitesimal invariant and vector bundles
Gian Pietro Pirola, Cecilia Rizzi
We study the Saito-Ikeda infinitesimal invariant of the ccle defined by curves in their jacobians using rank (k+1) vector bundles and we give a criterion for which the higher cycle…
Electronic screening and correlated superconductivity in carbon nanotubes
S. Bellucci, M. Cini, P. Onorato +1
A theoretical analysis of the superconductivity observed recently in Carbon nanotubes is proposed. We argue that ultra-small (diameter ) single wall carbon nanotubes…
Quenching of Spin Hall Effect in Ballistic nano-junctions
S. Bellucci, P. Onorato
We show that a nanometric four-probe ballistic junction can be used to check the presence of a transverse spin Hall current in a system with a Spin Orbit coupling not of the Rashba…
Beam-helicity asymmetry in photon and pion electroproduction in the Delta(1232) resonance region at Q^2= 0.35 (GeV/c)^2
A1 Collaboration, I. K. Bensafa, P. Achenbach +40
The beam-helicity asymmetry has been measured simultaneously for the reactions (e p \to e p γ) and (e p \to e p π^0) in the resonance region at 0.35 (GeV/c). T…
Drell-Yan processes, transversity and light-cone wavefunctions
B. Pasquini, M. Pincetti, S. Boffi
The unpolarized, helicity and transversity distributions of quarks in the proton are calculated in the overlap representation of light-cone wavefunctions truncated to the lowest or…
On a stochastic version of Prouse model in fluid dynamics
B. Ferrario, F. Flandoli
A stochastic version of a modified Navier-Stokes equation (introduced by Prouse) is considered in a 3-dimensional torus. We prove existence and uniqueness of martingale solutions.…
