Abstract

In this paper we investigate the quantum phase transition of the XXZ spin- Heisenberg model in presence of magnetic field term.To investigate the entanglement of states, we use of negativity as a measure to detect of states. We use the magnetization or magnetic susceptibility as a order parameter. We separately discuss and cases and compare together.

Persian Title: گذار فاز کوانتومی در مدل ¬هایزنبرگ XXZ اسپین 2/1 با استفاده از سنجه منفیت
Persian Abstract: دراین مقاله ، گذار فاز کوانتومی مدل هایزنبرگ XXZ اسپین 2/1 در حضور میدان مغناطیسی را بررسی می کنیم. از سنجه منفیت برای بررسی میزان درهم تنیدگی حالت ها استفاده می .کنیم. مغناطش و یا پذیرفتاری مغناطیسی را به عنوان پارامتر نظم به کار می بریم. دو حالت و و را جداگانه بحث کرده و با هم مقایسه می کنیم.
