Abstract
The generation of entanglement in an open system is studied in a model consisting of two independent Gaussian parties sharing a conventional heat bath environment. Reservoirs of this type appear in a broad class of condensed phase systems and themselves are insufficient to generate entanglement from initially separable states. Already local driving by an external classical field, however, is sufficient to promote this system-bath interaction to a source of entanglement. The presence or absence of the effect depends on the specific pulse shape of the external control, which we determine through optimal-control techniques.
