Hidden Antipolar Order Parameter and Entangled Neel-Type Charged Domain Walls in Hybrid Improper Ferroelectrics
M. H. Lee, C. -P. Chang, F. -T. Huang +5
Hybrid improper ferroelectricity (HIF) denotes a new class of polar instability by the mixture of two octahedral-distortion modes and can feature the coexistence of abundant head-t…
Sodium layer chiral distribution and spin structure of NaNiTeO with a honeycomb network
Sunil K. Karna, Y. Zhao, R. Sankar +7
The nature of Na ion distribution, diffusion path, and the spin structure of -type NaNiTeO with a Ni honeycomb network has been explored. The nuclear density distri…
Second-harmonic generation and linear electro-optical coefficients of SiC polytypes and nanotubes
I. J. Wu, G. Y. Guo
The second-order nonlinear optical susceptibility () and linear electro-optical coefficient () of a large number of single-walled zigzag, armchair and chira…
Conserved Spin and Orbital Angular Momentum Hall Current in a Two-Dimensional Electron System with Rashba and Dresselhaus Spin-orbit Coupling
Tsung-Wei Chen, Chih-Meng Huang, G. Y. Guo
We study theoretically the spin and orbital angular momentum (OAM) Hall effect in a high mobility two-dimensional electron system with Rashba and Dresselhuas spin-orbit coupling by…
Second-harmonic generation and linear electro-optical coefficients of BN nanotubes
G. Y. Guo, J. C. Lin
A systematic {\it ab initio} study of the second-order nonlinear optical properties of BN nanotubes within density functional theory in the local density approximation has been per…
Nature of Orbital Ordering in La_0.5Sr_1.5MnO_4 is Studied by Soft X-ray Linear Dichroism
D. J. Huang, W. B. Wu, G. Y. Guo +9
We found that the conventional model of orbital ordering of 3x^2-r^2/3y^2-r^2 type in the eg states of La_0.5Sr_1.5MnO_4 is incompatible with measurements of linear dichroism in th…
