Magnetic Properties of XXZ Heisenberg Antiferromagnetic and Ferrimagnetic Nanotubes被引量：1
《Communications in Theoretical Physics》2018年第12期823-828,共6页Zheng-Nan XianYu An Du 
Supported by the National Nature Science Foundation of China under Grant No.11772090
The spin-1/2 antiferromagnetic and spin-(1/2, 1) ferrimagnetic single-walled nanotubes are described by XXZ Heisenberg model. The sublattice magnetization and the critical temperature of the system are calculated by u...

Thermal Entanglement of a Two-Qubit XXZ Heisenberg Chain with Dzialoshinski-Moriya Interaction被引量：1
《Communications in Theoretical Physics》2009年第11期817-819,共3页QIAN Li FANG Jian-Xing 
Supported by the National Natural Science Foundation of China under Grant No.10774108;the Special Research Foundation for the Doctoral Program of Higher Education under Grant No.20050285002
The effect of DziaJoshinski-Moriya （DM） interaction on thermal entanglement of a two-qubit XXZ spin chain in a homogenous magnetic field is investigated. It is found that the DM interaction can enhance thermal entan...
