A DFT+DMFT study of the electronic structure of Samarium
Shengsong Xu, Zhenfeng Ouyang, Li Huang +1
The electronic structure of Samarium (Sm) was calculated using the density functional theory combined with the single-site dynamical mean-field theory. In this work, we investigate…
Electron-phonon coupling of one-dimensional (3,0) carbon nanotube
Zhenfeng Ouyang, Jing Jiang, Jian-Feng Zhang +3
A very recent report claims that ambient-pressure high-temperature () superconductivity was found in boron-doped three-dimensional networks of carbon nanotubes (CNTs). Here, w…
Strongly correlated altermagnet CaCrO
Zhenfeng Ouyang, Peng-Jie Guo, Rong-Qiang He +1
Altermagnetism, a newly discovered magnetic phase, has spurred growing research activity. Studies from a perspective of dynamical electronic correlation still remain scarce. Employ…
Phase diagrams and two key factors to superconductivity of Ruddlesden-Popper nickelates
Zhenfeng Ouyang, Rong-Qiang He, Zhong-Yi Lu
The discovery of superconductivity in Ruddlesden-Popper (RP) nickelates has drawn great attention. Many works have been done to study the superconductivity as well as to find more…
High-temperature superconductivity in LiAuH mediated by strong electron-phonon coupling under ambient pressure
Zhenfeng Ouyang, Bo-Wen Yao, Xiao-Qi Han +3
We used our developed AI search engine~(InvDesFlow) to perform extensive investigations regarding ambient stable superconducting hydrides. A cubic structure LiAuH with Au-H…
DFT+DMFT study of correlated electronic structure in the monolayer-trilayer phase of LaNiO
Zhenfeng Ouyang, Jia-Ming Wang, Rong-Qiang He +1
By preforming DFT+DMFT calculations, we systematically investigate the correlated electronic structure in the newly discovered monolayer-trilayer (ML-TL) phase of LaNiO…
