Abstract
We demonstrate the adjusting left-handedness in the cold Rb atom by its number density, the strong coupling field and two incoherent pumping fields. The results show that more dense Rb atoms and more stronger coupling field can influence the left-handedness more greatly, while the increasing two incoherent pumping fields construct the negative magnetic response but depress the negative electric response. The left-handedness adjusted by multiple parameter in the cold Rb atomic system provides the flexibility and feasibility for the coming experiment.
