In the last decades, unprecedented progress in the manipulation of the spin angular momentum (SAM) and orbital angular momentum (OAM) of light has been achieved, enabling a number of applications, ranging from classical ...

We investigate the exact dynamics of a system of two independent harmonic oscillators coupled through their angular momentum. The exact analytic solution of the equations of motion for the field operators is derived, and ...

In a theoretical approach, the complete and incomplete fusions are investigated by considering the Li-8 + Pb-208 reaction, within a three-body model where the projectile is described as n-Li-7 with binding energy epsilon(b). ...

In a recent contribution our group proposed a perturbative approach to deal with the open problem of double ionization of helium by electron impact. The goal of this work is to delve into the physics of the scattering ...
