共形扰动缺陷的熵

Entropy of conformal perturbation defects

Anatoly Konechny, Cornelius Schmidt-Colinet

摘要:

我们考虑半平面上的相关算子扰动二维共形场论(CFT)得到的扰动缺陷。如果扰动体理论流到另一个CFT描述的红外固定点,则缺陷流到紫外和红外固定点CFT之间的共形缺陷。对于连接理论空间中两个相邻不动点的短体重整化群流,我们得到了相应共形扰动亏损的边界熵的普适扰动公式。我们将我们的公式给出的邻近Virasoro极小模型Mm之间的流动的边界熵值与Gaiotto在[1]中构造的缺陷的边界熵值进行比较,并在1/m展开中的前两个阶处找到匹配。

英文摘要:

We consider perturbation defects obtained by perturbing a 2D conformal field theory (CFT) by a relevant operator on a half-plane. If the perturbed bulk theory flows to an infrared fixed point described by another CFT, the defect flows to a conformal defect between the ultraviolet and infrared fixed point CFTs. For short bulk renormalization group flows connecting two fixed points which are close in theory space we find a universal perturbative formula for the boundary entropy of the corresponding conformal perturbation defect. We compare the value of the boundary entropy that our formula gives for the flows between nearby Virasoro minimal models Mm with the boundary entropy of the defect constructed by Gaiotto in [1] and find a match at the first two orders in the 1/m expansion.
