Conformal Nature of Quantum Phase Transitions via Fuzzy Three-Sphere Regularization
Xue Meng, Liangdong Hu, Wei Zhu
Conformal field theory (CFT) offers a modern viewpoint for understanding phase transitions. However, directly accessing the conformal algebra and microscopically uncovering the eme…
Disorder Effects on the Quasiparticle and Transport Properties of Two-Dimensional Dirac Fermionic Systems

Despite extensive existing studies, a complete understanding of the role of disorder in affecting the physical properties of two-dimensional Dirac fermionic systems remains a stand…
Electromagnetic signatures of chiral quantum spin liquid
Saikat Banerjee, Wei Zhu, Shi-Zeng Lin
Quantum spin liquid (QSL) has become an exciting topic in interacting spin systems that do not order magnetically down to the lowest experimentally accessible temperature; however,…
Uncovering conformal symmetry in the Ising transition: State-operator correspondence from a fuzzy sphere regularization
Wei Zhu, Chao Han, Emilie Huffman +2
The Ising transition, the most celebrated and unsolved critical phenomenon in nature, has long been conjectured to have emergent conformal symmetry, similar to the case of the…
Circular dichroism in high-order harmonic generation: Heralding topological phases and transitions in Chern insulators
Alexis Chacón, Dasol Kim, Wei Zhu +10
Topological materials are of interest to both fundamental science and advanced technologies, because topological states are robust with respect to perturbations and dissipation. Ex…
