We consider the nonequilibrium dynamics of an interacting spin-1/2 fermiongas in a one-dimensional optical lattice after switching off the confiningpotential. In particular, we study the creation and the time evolution ofspatially separated, spin-entangled fermionic pairs. The time-dependentdensity-matrix renormalization group is used to simulate the time evolution andevaluate the two-site spin correlation functions, from which the concurrence iscalculated. We find that the typical distance between entangled fermionsdepends crucially on the onsite interaction strength, and that a time-dependentmodulation of the tunneling amplitude can enhance the production ofspin-entanglement. Moreover, we discuss the prospects of experimentallyobserving these phenomena using spin-dependent single-site detection.
