精确重整化群形式下复合算子的乘积

Products of composite operators in the exact renormalization group formalism

C. Pagani, H. Sonoda

摘要:

讨论了利用精确重整化群构造复合算子乘积的一般方法。主要考虑在重整化群的一般不动点上的Wilson作用量,证明了算子乘积的短程展开式的有效性.我们展示了如何通过求解微分方程来计算展开系数,并通过一些简单的例子来测试我们的方法。

英文摘要:

We discuss a general method of constructing the products of composite operators using the exact renormalization group formalism. Considering mainly the Wilson action at a generic fixed point of the renormalization group, we give an argument for the validity of short distance expansions of operator products. We show how to compute the expansion coefficients by solving differential equations, and test our method with some simple examples.
