Author(s): Yin Wang, Yong Ge, Yu-Jing Lu, Shuai Gu, Yi-Jun Guan, Qiao-Rui Si, Shou-Qi Yuan, Qiang Wang, Hong-Xiang Sun, and Haoran XueThe interplay between real-space topological lattice defects and momentum-space band topology can lead to new topological states. Here, the authors demonstrate that disclinations in acoustic valley-Hall crystals can induce...
Author(s): Hao-Hang Xu, Jian Liu, L. L. Tao, Xian-Jie Wang, Sergey V. Streltsov, and Yu SuiWe investigated spin-lattice coupling in orthorhombic pseudobrookite FeTi2O5 single crystal with highly ordered Fe2+/Ti4+ occupation, which consists of quasi-one-dimensional (1D) S=2 chains running along the a axis. Both the magnetization and specific heat measurements...
Author(s): N. R. S. van Venrooij, A. R. da Cruz, R. S. R. Gajjela, P. M. Koenraad, Craig E. Pryor, and Michael E. FlattéWe find the fine structure splitting (FSS) of a single exciton, which splits its degenerate ground-state manifold into singlets, nearly vanishes in highly asymmetric quantum dots (QDs) due to the cancellation of splitting effects with...
Author(s): N. J. Harmon, E. Z. Kurth, D. Coleman, and L. FlaniganIn the 100 years since the Stern-Gerlach experiment, ideas to use inhomogeneous magnetic fields for spintronics have been rare. In the theory here, the authors consider an inverse Stern-Gerlach effect in solid state systems of reduced dimension, in which charge current is produced by an...
Author(s): Chan Bin Bark, Youngseok Kim, and Moon Jip ParkChiral edge states in a quantum Hall effect are the paradigmatic example of a quasiparticle with chirality. In even space-time dimensions, the Nielsen-Ninomiya theorem strictly forbids chiral states in physical isolation. The exceptions to this theorem only occur in the presence of nonlocality,...
Author(s): Hanlin Wu, Sheng Li, Yan Lyu, Yucheng Guo, Wenhao Liu, Ji Seop Oh, Yichen Zhang, Sung-Kwan Mo, Clarina dela Cruz, Robert J. Birgeneau, Keith M. Taddei, Ming Yi, Li Yang, and Bing LvGrowth parameters play a significant role in the crystal quality and physical properties of layered materials. Here we present a case study on a van der Waals...
