Quantum Spin Dynamics Due to Strong Kitaev Interactions in the Triangular-Lattice Antiferromagnet CsCeSe
Tao Xie, S. Gozel, Jie Xing +8
The extraordinary properties of the Kitaev model have motivated an intense search for new physics in materials that combine geometrical and bond frustration. In this work, we emplo…

Stripe magnetic order and field-induced quantum criticality in the perfect triangular-lattice antiferromagnet CsCeSe
Tao Xie, Nan Zhao, S. Gozel +13
The two-dimensional triangular-lattice antiferromagnet (TLAF) is a textbook example of frustrated magnetic systems. Despite its simplicity, the TLAF model exhibits a highly rich an…

Helical Spin Dynamics in Commensurate Magnets: a Study on Brochantite, CuSO(OH)
S. E. Nikitin, Tao Xie, A. Gazizulina +8
We report the direct observation of a commensurate-ordered antiferromagnetic (AFM) state but incommensurate helical spin dynamics in the natural mineral brochantite CuSO(OH…
