Fortuitous Universality of Bose-Kondo Impurities
Abhijat Sarma, Zheng Zhou, Ryan A. Lanzetta +1
We use the fuzzy-sphere approach to study the Bose-Kondo impurity problem, namely a spin- impurity coupled to the -dimensional Wilson-Fisher CFT (Heisenberg univer…
Generalizing Deconfined Criticality to 3D -Flavor Quantum Chromodynamics on the Fuzzy Sphere
Emilie Huffman, Zheng Zhou, Yin-Chen He +1
The infra-red behaviour of gauge theories coupled to matter remains an open problem in quantum field theory. For a given gauge group, such theories are expected to flow to an inter…
Chern-Simons-matter conformal field theory on fuzzy sphere: Confinement transition of Kalmeyer-Laughlin chiral spin liquid
Zheng Zhou, Chong Wang, Yin-Chen He
Gauge theories compose a large class of interacting conformal field theories in 3d, among which an outstanding category is critical Chern-Simons-matter theories. In this paper, we…
Free real scalar CFT on fuzzy sphere: spectrum, algebra and wavefunction ansatz
Yin-Chen He
We introduce a simple model to realize the free real scalar CFT on the fuzzy sphere. The model is structurally similar to the original model that realizes the 3D Ising CFT on the f…
A new series of 3D CFTs with global symmetry on fuzzy sphere
Zheng Zhou, Yin-Chen He
The quest to discover new 3D CFTs has been intriguing for physicists. For this purpose, fuzzy sphere reguarlisation that studies interacting quantum systems defined on the lowest L…
