isn't negative absolute temperature an oxymoron?

  No. Temperature is just the relationship between entropy and energy: ∂S/∂E. This relationship can be negative.

    Ok, this is at atomical level, it is possible to increase the energy of the system till you freeze the electrons? What would happen then if the particles are organized at subatomical levels?. And below that? Could it be a way to study matter properties?(in place of the cern way)
