Thermal entanglement of the mixed spin-1/2 and spin-5/2 Heisenberg model under an external magnetic field ×÷Õß:Guo, KT (Guo, Ke-Tao)[ 1 ] ; Xiang, SH (Xiang, Shao-Hui)[ 1 ] ; Xu, HY (Xu, Hong-Yu)[ 1 ] ; Li, XH (Li, Xiao-Hong)[ 1 ] QUANTUM INFORMATION PROCESSING ¾í: 13 ÆÚ: 7 Ò³: 1511-1521 DOI: 10.1007/s11128-014-0745-7 ³ö°æÄê: JUL 2014 ²é¿´ÆÚ¿¯ÐÅÏ¢ ÕªÒª We use the concept of negativity to study the entanglement of spin-1/2 and spin-5/2 antiferromagnetic Heisenberg model with an inhomogeneous magnetic field. Analytical conclusions of the model are acquired. It is found that the critical temperature T-c goes up, as the increase of anisotropy parameter k. The temperature T-c becomes bigger than the results of spin-1/2 and spin-3/2 Heisenberg XXZ chain for the same value of k. And we can gain more entanglement at higher temperature by coordinating the value of inhomogeneity b. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:Entanglement; Mixed-spin; Negativity KeyWords Plus:QUANTUM INFORMATION; SEPARABILITY; COMPUTATION; COMPUTER; STATES; DOTS ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Guo, KT (ͨѶ×÷Õß) [ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ] Jiangxi Univ Sci & Technol, Sch Appl Sci, Ganzhou 341000, Peoples R China. µØÖ·: [ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ] [ 1 ] Jiangxi Univ Sci & Technol, Sch Appl Sci, Ganzhou 341000, Peoples R China µç×ÓÓʼþµØÖ·:guoketao@gmail.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ Scientific Research Program of Jiangxi University of Science and Technology jxxj12160 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ SPRINGER, 233 SPRING ST, NEW YORK, NY 10013 USA Àà±ð / ·ÖÀà Ñо¿·½Ïò hysicsWeb of Science Àà±ð hysics, Multidisciplinary; Physics, MathematicalÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000337604800003 ISSN: 1570-0755 eISSN: 1573-1332 ÆÚ¿¯ÐÅÏ¢ Ŀ¼£º Current Contents Connect® Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: AJ3YR Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 19 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 2 |
