Magnetic Field-Tunable Repulsive Exciton-Exciton Interaction in the van der Waals Antiferromagnet NiPS
Kaiyang Huang, Jaena Park, Zhuo Yang +4
Two ultra-narrow absorption peaks around 1.5 eV, which are widely believed to originate from a transition from a spin-orbital entangled triplet to a singlet state, in the two-dimen…
Topological phase transition driven by Hatsugai-Kohmoto interaction on the Kagome lattice
Zhuo-Xuan Yang, Jiangfan Wang
The interplay between band topology and strong correlations is central to modern condensed matter physics, but exact solutions are rare. Here, we present an exactly solvable model…
Possible evidence for Harper broadening in the yellow exciton series of Cu2O at ultrahigh magnetic fields
Zhuo Yang, Jinbo Wang, Yuto Ishii +3
Hydrogen-like systems in ultra-high magnetic fields are of significant interest in interdisciplinary research. Previous studies have focused on the exciton wavefunction shrinkage u…
Spin-supersolidity induced quantum criticality and magnetocaloric effect in the triangular-lattice antiferromagnet RbCo(SeO)
Yi Cui, Zhanlong Wu, Zhongcen Sun +12
We performed high-field magnetization, magnetocaloric effect (MCE), and NMR measurements on the Ising triangular-lattice antiferromagnet RbCo(SeO). The observations of…
Miniaturized and robust tunable monochromatic magneto-optical platform for pulsed magnetic fields
Lev Bergsma, Zhuo Yang, Bei Sun +6
Tunable monochromatic magneto-transmission is one of the most established magneto-optical techniques, particularly well suited for pulsed magnetic fields. It employs fixed-waveleng…
Dominant Kitaev Interaction and Field-induced Quantum Disordered Phase in the Cobaltate NaCoTeO
Xu-Guang Zhou, Han Li, Chaebin Kim +11
The identification of quantum spin liquid phases in Kitaev candidate materials remains a major experimental challenge. Since most Kitaev candidates develop antiferromagnetic (AFM)…
