New Results on the Phase Diagram of the FFXY Model: A Twisted CFT Approach

G. Cristofano, V. Marotta, P. Minnhagen, A. Naddeo, G. Niccoli

摘要:

由于连续自由度和离散自由度之间的复杂相互作用,完全阻挫XY(FFXY)模型中相变的数量、性质和顺序是一个非常重要的问题。在这篇文章中,我们攻击这样一个问题的扭曲共形场论(CFT)的方法,并显示它如何引起U(1)$\otimes Z_{2}$对称性和整个频谱的FFXY模型的激发。

英文摘要:

The issue of the number, nature and sequence of phase transitions in the fully frustrated XY (FFXY) model is a highly non trivial one due to the complex interplay between its continuous and discrete degrees of freedom. In this contribution we attack such a problem by means of a twisted conformal field theory (CFT) approach and show how it gives rise to the U (1)$\otimes Z_{2}$ symmetry and to the whole spectrum of excitations of the FFXY model.
