Doublon–holon pair creation in Mott–Hubbard systems in analogy to QED

Via the hierarchy of correlations, we study doublon–holon pair creation in the Mott state of the Fermi–Hubbard model (in higher dimensions) induced by a time-dependent electric field. Special emphasis is placed on the analogy to electron–positron pair creation from the vacuum in quantum electrodynam...
