非紧共形场论和III区的a_2 ^{(2)}(Izergin-Korepin)模型

Non compact conformal field theory and the a_2^{(2)} (Izergin-Korepin) model in regime III

Eric Vernier, Jesper Lykke Jacobsen, Hubert Saleur

摘要:

所谓的a_2 ^{(2)} Izergin-Korepin 19-顶点模型的第三阶段多年来一直无法理解。本文表明,它的连续极限实际上涉及到一个非紧的共形场论(所谓的威滕欧几里德黑洞CFT),这导致了一个连续谱谱的临界指数,以及非常强的校正标度。详细的数值证据的基础上的贝特anonymous分析,特别是涉及观察离散状态的频谱,完全符合弦论预测的黑洞CFT。我们的结果对O(n)模型的物理学有重要的影响,这将在其他地方讨论。

英文摘要:

The so-called regime III of the a_2^{(2)} Izergin-Korepin 19-vertex model has defied understanding for many years. We show in this paper that its continuum limit involves in fact a non compact conformal field theory (the so-called Witten Euclidian black hole CFT), which leads to a continuous spectrum of critical exponents, as well as very strong corrections to scaling. Detailed numerical evidence based on the Bethe ansatz analysis is presented, involving in particular the observation of discrete states in the spectrum, in full agreement with the string theory prediction for the black hole CFT. Our results have important consequences for the physics of the O(n) model, which will be discussed elsewhere.
