Composite Boson Theory of Fractional Chern Insulators
Guangyu Yu, Zheng Zhu
The understanding of fractional Chern insulators (FCIs) has been deeply guided by band topology and quantum geometry. Here, we introduce a real-space theoretical framework in which…
Multi-target density matrix renormalization group for 3D CFTs on the fuzzy sphere
Jin-Xiang Hao, Zheng Zhu, Yang Qi
The fuzzy sphere regularization provides a powerful framework for studying three-dimensional (3D) conformal field theories (CFTs) by mapping them onto numerically tractable lattice…
Spin-Based True Random Number Generation Enabled by Voltage-Amplified Quantum Fluctuations
Jie Zheng, Jiyong Kang, Zheng Zhu +6
We investigate spin quantum-fluctuation effects that originate from the Heisenberg uncertainty principle during the dynamical cycle of disentanglement, entanglement, and re-disenta…
Deconfined Quantum Critical Point in Quantum Hall Bilayers
Guangyu Yu, Tao Xiang, Zheng Zhu
Deconfined quantum critical points (DQCPs) represent an unconventional class of quantum criticality beyond the Landau-Ginzburg-Wilson-Fisher paradigm. Nevertheless, both their theo…
