Dr Gribakin’s research interests are in theoretical atomic physics and matter-antimatter interactions. His main research interests are in various elementary atomic processes that arise in collisions between positrons and atoms or molecules (scattering, annihilation), electrons and positive ions (recombination), photons and atoms or negative ions (photoionisation and photodetachment), in particular for strong laser fields, as well as cold-atom collisions and many-body quantum chaos. He also have an interest in the problem of positron-atom and positron-molecule binding and resonances, and in low-energy positronium scattering from atoms.
