Thermal and ground-state entanglement in the supermolecular dimer [Mn4]2
2006
Abstract In this Letter, we investigate numerically the entanglement in the supermolecular dimer [Mn 4 ] 2 consisting of a pair of single molecular magnets with antiferromagnetic exchange-coupling. The measure of entanglement “Negativity” as a function of magnetic field is calculated explicitly for various cases. The entanglement of thermal and ground state as a function of the external field and temperature is discussed.
