Field-induced multipolar character in the dipolar ground state of the honeycomb rare-earth chalcohalide NdOF
Tiantian Liu, Yanzhen Cai, Mingtai Xie +6
Field-tunable reconstruction of crystalline electric field (CEF) doublets offers a promising avenue for inducing multipolar character, while its observation in real materials has b…
Emergent Dispersive Multipolar Excitations in NaErSe
Zheng Zhang, Mingfang Shu, Mingtai Xie +6
In most condensed-matter systems, local and collective excitations remain decoupled due to their distinct energy scales. Here, we identify coupled local-collective excitations in t…
Anomalous enhancement of magnetism by nonmagnetic doping in the honeycomb-lattice antiferromagnet ErOCl
Yanzhen Cai, Mingtai Xie, Jing Kang +8
Tuning magnetic anisotropy through chemical doping is a powerful strategy for designing functional materials with enhanced magnetic properties. Here, we report an enhanced Er^3+ ma…
Dominant Kitaev interaction and field-induced quantum phase transitions in triangular-lattice KCeSe2
Mingtai Xie, Zheng Zhang, Weizhen Zhuo +13
Realizing Kitaev interactions on triangular lattices offers a compelling platform for exploring quantum-spin-liquid physics beyond the conventional honeycomb lattice framework. Her…
Gapless spinon excitations emerging from a multipolar transverse field in the triangular-lattice Ising antiferromagnet NaTmSe2
Zheng Zhang, Jinlong Jiao, Weizhen Zhuo +9
The triangular-lattice quantum Ising antiferromagnet is a promising platform for realizing Anderson's quantum spin liquid, though finding suitable materials to realize it remains a…
