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…
Reclaiming the Lost Conformality in a non-Hermitian Quantum 5-state Potts Model
Yin Tang, Han Ma, Qicheng Tang +2
Conformal symmetry, emerging at critical points, can be lost when renormalization group fixed points collide. Recently, it was proposed that after collisions, real fixed points tra…
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…
Floquet Flux Attachment in Cold Atomic Systems
Helia Kamal, Jack Kemp, Yin-Chen He +4
Flux attachment provides a powerful conceptual framework for understanding certain forms of topological order, including most notably the fractional quantum Hall effect. Despite it…
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…
Quantum Monte Carlo Simulation of the 3D Ising Transition on the Fuzzy Sphere
Johannes S. Hofmann, Florian Goth, Wei Zhu +2
We present a numerical quantum Monte Carlo (QMC) method for simulating the 3D phase transition on the recently proposed fuzzy sphere [Phys. Rev. X 13, 021009 (2023)]. By introducin…
