Strong-field-QED analogue on the lattice — Ralf Schützhold and •Nikodem Szpak — Fakultät für Physik, Universität Duisburg-Essen

We present a model describing cold atoms in an optical lattice which is capable of showing phenomena known from the strong field QED, like the Schwinger effect or adiabatic spontaneous pair creation. This requires re-derivation of an effective Fermi-Hubbard Hamiltonian from first principles. The main advantage of this analogue model is experimental accessibility of the strong field regime in contrast to the real QED.
