ABSTRACT:
Dzyaloshiniskii-Moriya (DM) interaction
in three directions (Dx, Dy and Dz) is used to generate entangled network from partially entangled states in the presence of the
spin-orbit coupling. The effect of the spin coupling on the entanglement between any two nodes of
the network is investigated. The entanglement
is quantified using Woottores concurrence method. It is shown that the
entanglement decays as the coupling increases. For larger values of the spin
coupling, the entanglement oscillates within
finite bounds. For the initially entangled channels, the upper bound does not
exceed its initial value, whereas the entanglement reaches its maximum value
for the channels generated via indirect interaction.
