在共形场理论的极限条件下,研究了临界XXZ自旋链的Grassmann结构。利用Zamolodchikov的运动积分和两类费米子产生算子,提出了一种新的Virasoro Verma模的描述。与通常的维拉索罗描述的确切关系一直持续到第6级。
The Grassmann structure of the critical XXZ spin chain is studied in the limit to conformal field theory. A new description of Virasoro Verma modules is proposed in terms of Zamolodchikov’s integrals of motion and two families of fermionic creation operators. The exact relation to the usual Virasoro description is found up to level 6.
