Scientific paper

We investigate entanglement properties in dimerized and frustrated spin-one models by applying the concept of negativity. On the basis of the relation between negativity and correlators, negativities are numerically calculated. We study the effects of dimerization and frustration on entanglement. We also consider the case of finite temperature, and determine the threshold temperature before which the thermal state is doomed to be entangled.
