广义Lunin-Maldacena背景下的可积非齐次自旋链

Integrable Inhomogeneous Spin Chains in Generalized Lunin-Maldacena Backgrounds

Matheus Jatkoske Lazo

摘要:

本文用矩阵积方法得到了最一般的具有最近邻相互作用和$U(1)^2$和$U(1)^3$对称性的非均匀自旋链的精确解。这些模型与Leigh-Strassler变形的N=4 SYM理论的单圈混合矩阵有关,与广义Lunin-Maldacena背景下的IIB型弦论对偶,分别在两种和三种场的扇区内.本文给出的解推广了作者在N=2和N=3扇区内具有$U(1)^N$对称性的齐次自旋链的结果。

英文摘要:

We obtain through a Matrix Product Ansatz the exact solution of the most general inhomogeneous spin chain with nearest neighbor interaction and with $U(1)^2$ and $U(1)^3$ symmetries. These models are related to the one loop mixing matrix of the Leigh-Strassler deformed N=4 SYM theory, dual to type IIB string theory in the generalized Lunin-Maldacena backgrounds, in the sectors of two and three kinds of fields, respectively. The solutions presented here generalizes the results obtained by the author in a previous work for homogeneous spins chains with $U(1)^N$ symmetries in the sectors of N=2 and N=3.
