Abstract
We show how strong steady-state entanglement can be achieved in a three-mode optomechanical system (or other parametrically-coupled bosonic system) by using one of the modes as a cold reservoir to effectively laser-cool a delocalized Bogoliubov mode. This approach allows one to surpass the bound on the maximum stationary intracavity entanglement possible with a coherent two-mode squeezing interaction. Unlike typical dissipative entanglement schemes, the entangling dynamics here are most effective in a regime where the effects of the engineered reservoir cannot be described by a Markovian Lindblad master equation.
