An implementation of the density functional perturbation theory in the PAW framework
Xiaoqiang Liu, Yihao Lin, Ji Feng
Quantifying materials' dynamical responses to external electromagnetic fields is central to understanding their physical properties. Here we present an implementation of the densit…
Charge doping to flat AgF2 monolayers in a chemical capacitor setup
Daniel Jezierski, Adam Grzelak, XiaoQiang Liu +5
Flat monolayers of silver II fluoride, which could be obtained by epitaxial deposition on an appropriate substrate, have been recently predicted to exhibit very strong antiferromag…
A silver(II) route to unconventional superconductivity
Xiaoqiang Liu, Shishir K. Pandey, Ji Feng
The highly unusual divalent silver in silver difluoride (AgF) features a nearly square lattice of Ag bridged by fluorides. As a structural and electronic analogue of cup…
Giant pressure-enhancement of multiferroicity in CuBr2
J. S. Zhang, Yiqi Xie, X. Q. Liu +16
Type-II multiferroic materials, in which ferroelectric polarization is induced by inversion non-symmetric magnetic order, promise new and highly efficient multifunctional applicati…
Zero-energy bound states in the high-temperature superconductors at the two-dimensional limit
Chaofei Liu, Cheng Chen, Xiaoqiang Liu +6
Majorana zero modes (MZMs) that obey the non-Abelian statistics have been intensively investigated for potential applications in topological quantum computing. The prevailing signa…
On the charge and magnetic ordering in monolayer NbSe: a first principles study
Feipeng Zheng, Zhimou Zhou, Xiaoqiang Liu +1
Monolayer NbSe has recently been shown to be a 2-dimensional superconductor, with a competing charge-density wave (CDW) order. This work investigates the electronic structure o…
Observation of Unusual Magnetoelastic Effects in a Quasi-1D Spiral Magnet
Chong Wang, Daiwei Yu, Xiaoqiang Liu +10
We present a systematic study of spin and lattice dynamics in the quasi-one-dimensional spiral magnet CuBr2, using Raman scattering in conjunction with infrared and neutron spectro…
