含缺陷Liouville理论的经典和半经典性质

On classical and semiclassical properties of the Liouville theory with defects

Hasmik Poghosyan, Gor Sarkissian

摘要:

详细分析了含拓扑亏损的Liouville理论的拉格朗日量,得到了相应的亏损运动方程的通解,并利用Bootstrap程序研究了已发现的亏损两点函数的重、轻半经典极限.我们证明了重渐近极限是由指数的Liouville行动的缺陷,评估的解决方案有两个奇点。我们证明了光的渐近极限是由能量动量张量为零的缺陷运动方程的解的有限维路径积分给出的。

英文摘要:

The Lagrangian of the Liouville theory with topological defects is analyzed in detail and general solution of the corresponding defect equations of motion is found. We study the heavy and light semiclassical limits of the defect two-point function found before via the bootstrap program. We show that the heavy asymptotic limit is given by the exponential of the Liouville action with defects, evaluated on the solutions with two singular points. We demonstrate that the light asymptotic limit is given by the finite dimensional path integral over solutions of the defect equations of motion with a vanishing energy-momentum tensor.
