Screening phonon-mediated superconductors from static orbital Hamiltonians
Jian-Feng Zhang, Ze-Feng Gao, Xiao-Qi Han +6
The first-principles search for superconductors is severely limited by the high cost of electron-phonon coupling (EPC) calculations. Here we develop a low-cost, physically transpar…
Bridging Crystal Structure and Material Properties via Bond-Centric Descriptors
Jian-Feng Zhang, Ze-Feng Gao, Xiao-Qi Han +7
Although chemical bonding is the fundamental mechanistic bridge connecting atomic structure to macroscopic material properties, current data-driven materials science largely treats…
Strain-triggered high-temperature superconducting transition in two-dimensional carbon allotrope
Tian Yan, Ru Zheng, Jin-Hua Sun +5
Driving non-superconducting materials into a superconducting state through specific modulation is a key focus in the field of superconductivity. Pressure is a powerful method that…
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…
Quantum anomalous Hall effect with high Chern number in two dimensional ferromagnets Ti2TeSO
Panjun Feng, Miao Gao, Xun-Wang Yan +1
Two-dimensional Chern insulators have emerged as crucial platforms for the realization of the quantum anomalous Hall effect, and as such have attracted significant interest in spin…
Type-II quantum spin Hall insulator
Panjun Feng, Chao-Yang Tan, Miao Gao +5
Quantum spin Hall effect is usually realized in two-dimensional materials with time-reversal symmetry, but whether it can be realized without symmetry protection remains unexplored…
