  In this article, we investigate the geometric discord of quantum states of
fermionic system in accelerated frame. It is shown by the method beyond the
single-mode approximation, depending on the region considered, that the
geometric discord for the entangled quantum states of fermionic system in
accelerated frame can vanish or be retained at the infinite acceleration limit:
it does not disappear when the quantum state of the
particle(Alice)-particle(Bob in region I) case or the
particle(Alice)-antiparticle(Bob in region II) is considered and it disappears
when the particle(Alice)-antiparticle(Bob in region I) case or the
particle(Alice)-particle(Bob in region II) one is considered.
