Localization and topological transitions in generalized non-Hermitian SSH models
X. Q. Sun, C. S. Liu
We study the localization and topological transitions of the generalized non-Hermitian SSH models, where the non-Hermiticities are introduced by the complex quasiperiodic hopping a…
Magnetic ordering phase transition and abnormal brittleness in dilute Fe-Mn solid solution
Wei Liu, Yunfeng Liang, Xiangyan Li +8
Experiments showed that solute Mn in bcc iron is in antiferromagnetic (AFM) coupling with iron neighbours below 2 at.% Mn, but is in ferromagnetic (FM) coupling at higher concentra…
The quantum phase transitions of dimer chain driven by an imaginary ac field
C. S. Liu
A topologically equivalent tight binding model is proposed to study the quantum phase transitions of dimer chain driven by an imaginary ac field. I demonstrate how the partner Hami…
Hydrogen bubble nucleation by self-clustering: Density Functional Theory and statistical models studies using tungsten as a model system
Jie Hou, Xiang-Shan Kong, Jingjing Sun +4
Low-energy hydrogen irradiation is known to induce bubble formation in tungsten, while its atomistic mechanisms remain little understood. Using first-principles calculations and st…
The impacts of the quantum-dot confining potential on the spin-orbit effect
Rui Li, Zhi-Hai Liu, Yidong Wu +1
For a nanowire quantum dot with the confining potential modeled by both the infinite and the finite square wells, we obtain exactly the energy spectrum and the wave functions in th…
Topologically nontrivial states in one-dimensional nonlinear bichromatic superlattices
C. S. Liu, Z. Z. Wang. Chuanhao Yin, Y. D. Wu +3
We study topological properties of one-dimensional nonlinear bichromatic superlattices and unveil the effect of nonlinearity on topological states. We find the existence of nontriv…
