Author(s): Hui-Jun Zhao, Fei Fan, Song-Lin Jiang, Xin-Hao Jiang, Yun-Yun Ji, and Sheng-Jiang Chang Liquid crystal (LC), an anisotropic and tunable material, is widely used in phase shifters, polarization converters, and chiral devices. However, it is difficult for simple LC devices to achieve strong chiral response in the terahertz regime, even for cholesteric LCs. In this paper, we observe a str… [Phys. Rev.

Author(s): D. Scheffler, O. Steuer, S. Zhou, L. Siegl, S. T. B. Goennenwein, and M. Lammel Magnetic garnets such as yttrium iron garnet (${\mathrm{Y}}_{3}{\mathrm{Fe}}_{5}{\mathrm{O}}_{12}$, YIG) are widely used in spintronic and magnonic devices. Their magnetic and magneto-optical properties can be modified over a wide range by tailoring their chemical composition. Here, we report the su… [Phys. Rev. Materials 7, 094405] Published Wed Sep...

Author(s): Emma H. Wolpert, Simon J. Cassidy, and Andrew L. Goodwin We revisit the problem of polytypism in layered ${MX}_{2}$ materials, with a view to reinterpreting the phase space accessible to this family. Our starting point is to develop a simple, constructive, and compact label for the most commonly observed stacking arrangements, similar to the Glazer notati… [Phys. Rev.

Author(s): Timo Lebeda, Thilo Aschebrock, Jianwei Sun, Linn Leppert, and Stephan Kümmel In density functional theory, traditional explicit density functionals such as the local density approximation and generalized gradient approximations cannot accurately predict the band gap of solids for a fundamental reason: They lack the exchange-correlation derivative discontinuity. By comparing … [Phys. Rev. Materials 7, 093803] Published Tue Sep 19...

Author(s): Ryo Tamura, Kei Terayama, Masato Sumita, and Koji Tsuda Based on available datasets prepared by numerical simulations and machine learning, maps of properties for materials that have not yet been synthesized can be developed. These maps can be used to select promising materials for synthetic experiments. With a single objective function, the ranking of t… [Phys. Rev. Materials 7, 093804] Published Tue Sep 19, 2023

Ovidiu Garlea, Clarina dela Cruz, Zhen Liu, Wenjing Niu, Leili Tan, Guanzhong Zhou, Fei Liu, Shuhan Zheng, Zhen Ma, Xiuzhang Wang, Hong Li, Shuai Dong, and Jun-Ming Liu We report a quasi-one-dimensional $S=1$ spin chain compound $\mathrm{BaNi}{\mathrm{Te}}_{2}{\mathrm{O}}_{7}$. This magnetic system has been investigated by magnetic susceptibility, specific heat, and neutron powder diffraction...
