Field-selected seven-site topological magnons in a classical frustrated triangular-lattice K-- magnet
Bin Xi, Jie Lu, Shun-Li Yu +1
Defining magnon topology in strongly frustrated magnets is often hindered by the absence of a simple harmonic magnon vacuum at zero field. Within a classical-spin ground-state sear…

Alternative -picture of bosonic fractional Chern insulators at high filling factors in multiple flat-band systems
Licheng Wang, Dong-Hao Guan, Ai-Lei He +2
Most fractional quantum Hall states have been traditionally identified within a single energy band, such as the lowest Landau level or topological flat band. As more particles are…

The possible frustrated superconductivity in the kagome superconductors
Hong-Min Jiang, Wen-Qian Dong, Shun-Li Yu +1
Geometric frustration has long been a subject of enduring interest in condensed matter physics. While geometric frustration traditionally focuses on magnetic systems, little attent…
