The fundamental indication of the departure of quantum mechanics from the classical world is the so-called quantum coherence. Typically, we define it as the characteristic of systems which are in a superposition of states yielding interference patter

This article continues and completes a recent one regarding a quantum version of van Cittert–Zernike's theorem (Fabre et al 2018 Eur. J. Phys. 39 015401). In that paper, we considered a mixture of quantum states that only differed in their initial

The double electron capture into the continuum states of the projectile (double ECC) is investigated theoretically in collisions of 100 keV He2+ ions with He atoms. The process is described within the framework of the impact parameter and frozen-corr

We review the concept of quantum vortices and their appearance in ionization collisions. By relaxing the usual geometrical restrictions on the momenta of the final-state, we study these vortices as submanifolds of codimension 2 in the space where the

In the study of collision processes, a series of conditions is usually assumed. One of them is that the beam of projectiles is coherent in lengths greater than those of the targets against which it strikes. However, recent experimental results and th

The phenomenon of bulk and surface plasmons in solids of different geometries is analyzed in detail, giving special consideration to Ritchie's pioneering works and his relevant contributions to the advance of the knowledge in the field. A review of p

We study the time evolution of an incoherent mixture of quantum states and demonstrate, in very simple terms, a quantum mechanical equivalent of van Cittert–Zernike theorem, which can be easily explained to Quantum Physics students with a basic kno

We study the role of the projectile coherence in collision processes. We analyze in particular the ionization of He by p+ and C6+ projectiles at 1 and 100 MeV/amu, respectively. We compare the influence of this effect in both cases by performing a Fi
