dc.description.abstract	Open systems acquire time-dependent coupling constants through interaction with an external field or environment. We generalize the Lewis–Riesenfeld invariant theorem to open system of quantum fields after second quantization. The generalized invariants and thereby the quantum evolution are found explicitly for time-dependent quadratic fermionic systems. The pair production of fermions is computed and other physical implications are discussed.	pt_BR
