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…

Universal Magnetocaloric Effect near Quantum Critical Point of Magnon Bose-Einstein Condensation
Junsen Xiang, Enze Lv, Qinxin Shen +19
Bose-Einstein condensation (BEC), a macroscopic quantum phenomenon arising from phase coherence and bosonic statistics, has been realized in quantum magnets. Here, we report the ob…
