Two Qubit Entanglement in Magnetic Chain with DM Antisymmetric Anisotropic Exchange Interaction
Zeynep Nilhan Gurkan, Oktay K. Pashaev
In the present paper we study two qubit entanglement in the most general Heisenberg magnetic chain with (non)homogeneous magnetic fields and the DM anisotropic antisymmetric…
