$T\bar{T}$ -变形可积场论中的Lax联络

Lax Connections in $T\bar{T}$-deformed Integrable Field Theories

Bin Chen, Jue Hou, Jia Tian

摘要:

本文尝试用两种不同的方法构造$T\bar{T}$ -变形可积场论的Lax联络。在合理的假设条件下,我们通过直接求解Lax方程组,在$T\bar{T}$变形的仿射Toda理论和主手征模型中,得到了相应的拉克斯对。这种方法很简单,但可能很难应用于一般模型。然后,我们利用动力学坐标变换从未变形理论中读出变形理论中的Lax联络。我们发现,一旦逆变换是可用的,Lax连接可以很容易地读取。我们明确的几类标量模型的建设,并找到一致性的第一种方式。

英文摘要:

In this work, we try to construct the Lax connections of $T\bar{T}$-deformed integrable field theories in two different ways. With reasonable assumptions, we make ansatz and find the Lax pairs in the $T\bar{T}$-deformed affine Toda theories and the principal chiral model by solving the Lax equations directly. This way is straightforward but maybe hard to apply for general models. We then make use of the dynamical coordinate transformation to read the Lax connection in the deformed theory from the undeformed one. We find that once the inverse of the transformation is available, the Lax connection can be read easily. We show the construction explicitly for a few classes of scalar models, and find consistency with the ones in the first way.
