Are vacuum fluctuations relevant in absorption dynamics?
Pedro Sancho
Vacuum fluctuations play a central role in spontaneous emission. Recently, it has been suggested that these fluctuations could also be fundamental in the absorption dynamics, break…

Symmetrisation effects on the correlation time delay
Pedro Sancho
We analyze the electronic correlation contribution to the time delay in the photo-ionization of the excited ortho- and para-Helium states. A simple estimation, based on the ionizat…

Entanglement of unstable atoms: modifications of the emission properties
Pedro Sancho, Luis Plaja
We analyse the influence of entanglement on the emission properties of atoms. To this end, first, we propose a scheme for the preparation of a pair of entangled Helium atoms, one i…
