Impurities with a cusp: general theory and 3d Ising
Gabriel Cuomo, Yin-Chen He, Zohar Komargodski
In CFTs, the partition function of a line defect with a cusp depends logarithmically on the size of the line with an angle-dependent coefficient: the cusp anomalous dimension. In t…

Entropic -function of 3D Ising conformal field theory via the fuzzy sphere regularization
Liangdong Hu, W. Zhu, Yin-Chen He
The -function, the three-dimensional counterpart of the central charge in the 2D conformal field theory, measures the effective number of degrees of freedom in 3D quantum field…

The -function and Defect Changing Operators from Wavefunction Overlap on a Fuzzy Sphere
Zheng Zhou, Davide Gaiotto, Yin-Chen He +1
Defects are common in physical systems with boundaries, impurities or extensive measurements. The interaction between bulk and defect can lead to rich physical phenomena. Defects i…
