ABSTRACT
It is shown that the reservoir engineering can be controlled by the collective phase Φ of three coherent fields interacting with a closed Δ-type atom. We find that the atomic system acts as a one-channel dissipation reservoir when Φ = 0(π), but it behaves as a two-channel dissipation reservoir for Φ ≠ 0(π). The phase-dependent reservoir engineering provides a convenient way to produce robust two-mode squeezing and entanglement, which may find potential applications in quantum information processing.
