用共形自助法求解变维临界伊辛模型

Critical Ising Model in Varying Dimension by Conformal Bootstrap

Andrea Cappelli, Lorenzo Maffi, Satoshi Okuda

摘要:

使用现有的SDPB和极值泛函方法,对维数4>d>2的几个值数值求解单相关共形自举。临界指数和其他共形数据的低洼状态得到的整个范围内的尺寸高达四位小数的精度,然后与现有的几个结果进行比较。引导扭转场的共形尺寸也被确定到高自旋,并且它们的d依赖性显示了共形态如何在d=2.2附近重新排列以匹配d=2极限中的Virasoro共形块。研究了3>d>2时伊辛点的态解耦,发现在d=3时一个结构常数的消失一直持续到d=2,在那里它对应于Virasoro零矢量条件。

英文摘要:

The single-correlator conformal bootstrap is solved numerically for several values of dimension 4>d>2 using the available SDPB and Extremal Functional methods. Critical exponents and other conformal data of low-lying states are obtained over the entire range of dimensions with up to four-decimal precision and then compared with several existing results. The conformal dimensions of leading-twist fields are also determined up to high spin, and their d-dependence shows how the conformal states rearrange themselves around d=2.2 for matching the Virasoro conformal blocks in the d=2 limit. The decoupling of states at the Ising point is studied for 3>d>2 and the vanishing of one structure constant at d=3 is found to persist till d=2 where it corresponds to a Virasoro null-vector condition.
