Abstract
We discuss the coupler system of two nonlinear oscillators excited by an external coherent field prepared in a maximally entangled state (Bell-like state). We show that as a result of the coupler interaction of the system with external broadband squeezed vacuum bath, entanglement decay dynamics can be considerably affected. Besides the phenomena of sudden entanglement death and its rebirth, a shortening (or lengthening) of the total disentanglement time τD can be observed, depending on the squeezing parameters. Moreover, in the example of one of the reborn entanglement cases it is shown that by changing the values of these parameters the maximal values of the negativity for the 3 ⊗ 2 system discussed can be tailored. © 2010 IOP Publishing Ltd.
