Renormalization Group and Critical Phenomena
-
摘要: 介绍了用重整化群方法描述临界现象的基本思路和做法. 指出重整化群方法确实抓住了临界现象的最重要的物理特征——自相似性， 并在此基础之上建立了一套切实可行的求解方案. The basic clue and the main steps of renormalization group method used for the description of critical phenomena is introduced. It is pointed out that this method really reflects the most important physical features of critical phenomena， i.e. self similarity，and set up a practical solving method from it. This way of setting up a theory according to the features of the physical system is really a good lesson for today’s physicists.Abstract: The basic clue and the main steps of renormalization group method used for the description of critical phenomena is introduced.
