Quantum correlations in a mixed spin-(1/2,1) Heisenberg dimer
Original language description
In this article, we consider the heterodinuclear complex [Ni(dpt)(H2O)Cu(pba)] center dot 2H(2)O [pba =1,3-propylenebis (oxamato) and dpt = bis-(3-aminopropyl)amine] realized through the theoretical model of mixed spin-(1/2,1) coupled via Heisenberg interaction. We study the behaviors of thermal quantum correlations of the above material via Measurement-Induced Nonlocality (MIN) based on Hilbert-Schmidt norm and fidelity. We observe that the quantum correlation measures increase with the magnetic field in an unconventional way. The role of system parameters is also brought out at thermal equilibrium. The highlight of the results is that we are able to show the existence of room temperature quantum correlation using fidelity based MIN whereas the entanglement ceases to exist at 141 K.
