Abstract

We study the geometric measure of quantum discord of total Dirac fields in noninertial frames As a comparison we also calculate the corresponding geometric measure of entanglement of the same system We discuss the properties of geometric measure of quantum discord and geometric measure of entanglement for this system with acceleration parameter and the parameter describing the entangle degree of the system in detail Our results show that from an overall perspective two geometric measures have similar behavior with the variation of the entangle parameter and the acceleration parameter We find that this tripartite system is monogamous for the geometric measure of quantum discord
