Bi-Yang-Baxter模型的复苏

Resurgence in the Bi-Yang-Baxter Model

Lucas Schepers, Daniel C. Thompson

摘要:

本文研究了$SU(2)$主手征模型(PCM)的可积bi-Yang-Baxter形变及其有限作用幺子解.在$S^1$的绝热紧化下,我们得到了一个具有椭圆型Lamé势的量子力学.我们对这个量子力学中的基态能量进行了大阶微扰计算,得到了一个渐近级数。使用Borel-Padé技术,我们确定的预期位置的分支切割的Borel平面的扰动系列,并表明它们匹配的值的uniton行动。因此,我们可以将非微扰对能量的贡献与在绝热紧化后分形的幺子解相匹配。WKB分析的一个分支是用$\mathcal{N}=2$ Seiberg-Witten理论来确定这种变形PCM的二次微分。这可以作为一个$N_f=4$ $SU(2)$理论或作为一个椭圆型的$SU(2)\times SU(2)$理论来完成。规范理论的质量参数由相变材料的形变参数给出。

英文摘要:

We study the integrable bi-Yang-Baxter deformation of the $SU(2)$ principal chiral model (PCM) and its finite action uniton solutions. Under an adiabatic compactification on an $S^1$, we obtain a quantum mechanics with an elliptic Lamé-like potential. We perform a perturbative calculation of the ground state energy in this quantum mechanics to large orders obtaining an asymptotic series. Using the Borel-Padé technique, we determine the expected locations of branch cuts in the Borel plane of the perturbative series and show that they match the values of the uniton actions. Therefore, we can match the non-perturbative contributions to the energy with the uniton solutions which fractionate upon adiabatic compactification. An off-shoot of the WKB analysis, is to identify the quadratic differential of this deformed PCM with that of an $\mathcal{N}=2$ Seiberg-Witten theory. This can be done either as an $N_f=4$ $SU(2)$ theory or as an elliptic quiver $SU(2)\times SU(2)$ theory. The mass parameters of the gauge theory are given by the deformation parameters of the PCM.
