Widom scaling (after Benjamin Widom) is a hypothesis in statistical mechanics regarding the free energy of a magnetic system near its critical point which leads to the critical exponents becoming no longer independent so that they can be parameterized in terms of two values. The hypothesis can be seen to arise as a natural consequence of the block-spin renormalization procedure, when the block size is chosen to be of the same size as the correlation length.〔Kerson Huang, Statistical Mechanics. John Wiley and Sons, 1987〕 Widom scaling is an example of universality. == Definitions == The critical exponents and are defined in terms of the behaviour of the order parameters and response functions near the critical point as follows :, for :, for : 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Widom scaling」の詳細全文を読む スポンサード リンク
