Abstract
- In this work, we study the time evolution of a coherent spin state under the action of a non-hermitian hamiltonian. The hamiltonian is modeled by a one-axis twisting term plus a Lipkin-type interaction. We show that when the Lipkin interaction is switched on, depending on the relative values of the coupling constants, the initial state evolves into a steady squeezed state which minimizes the Uncertainty Relations, Intelligent Spin State. We apply this result to look for the generation of an steady intelligent spin state from an ensemble of nitrogen vacancy colour centers in diamond coupled to a mechanical resonator.<br />Comment: arXiv admin note: text overlap with arXiv:1101.4828 by other authors
