Carrier duality from the convergence of Dirac fermions and high-order van Hove singularities
Meng Lyu, Kaiyi Zhai, Nikolai Peshcherenko +15
The convergence of highly mobile Dirac fermions and flat-band heavy electrons offers a paradigm for emergent quantum phenomena. However, experimental realization of such intriguing…
Cascade of Spin Liquids in a Bilayer Triangular-lattice Antiferromagnet Rb_2Co_2(SeO_3)_3
Xiaoyu Xu, Yunlong Wang, Xuejuan Gui +20
In frustrated Ising magnets, classical spin liquids (CSLs) with macroscopic ground-state degeneracy can survive against conventional magnetic order, as exemplified by systems on tr…
Robust Flat Magnetoresistivity in D0-FeGa Driven by Chiral Anomaly
Ruoqi Wang, Xinyang Li, Bo Zhao +11
Topologically non-trivial nodes emerging from flat-band crossings not only enhance unconventional topological responses but also play a fundamental role in exploring correlation-dr…
