有限体积II中的形状因子:不连通项和有限温度关联函数

Form factors in finite volume II:disconnected terms and finite temperature correlators

B. Pozsgay, G. Takacs

摘要:

继续在以前的工作中开始的调查,我们认为形状因子的可积量子场论在有限体积,扩展我们的调查矩阵元素与断开件。我们的结果提供了截断共形空间方法的数值验证。这样的矩阵元素是很重要的计算有限温度关联函数,我们给出了一个新的方法产生一个低温展开,我们测试的一点函数到三阶。

英文摘要:

Continuing the investigation started in a previous work, we consider form factors of integrable quantum field theories in finite volume, extending our investigation to matrix elements with disconnected pieces. Numerical verification of our results is provided by truncated conformal space approach. Such matrix elements are important in computing finite temperature correlation functions, and we give a new method for generating a low temperature expansion, which we test for the one-point function up to third order.
