Dynamics of Entanglement for Two-Electron Atoms
... the Coulombic repulsion and vice versa. Since for the initial condition the mean (square) distance between the electrons, corresponding to an atom with Z = 1.2, is larger than the mean distance in an atom with Z = 2 it is reasonable that a stronger potential will diminish this distance and, after ex ...

Electron phase coherence
... Usually it is assumed that in a magnetic field the sample properties change significantly. Thus one can think that at each magnetic field a sample represents a realization of an ensemble (so-called ergodic hypothesis) . Consequently, one can average over magnetic fields rather then over different sa ...

Electron–phonon interaction and electronic decoherence in
... to borrow some idea from the theory of solid state physics, it could be that coherent interactions between electrons and lattice distortions give rise to new effects such as assisted tunneling [8] or even superconductivity. Indeed both phenomena could give striking results in organic systems [9,10]. ...
