First-principles study of the superconductivity in LaO
Pei-Han Sun, Jian-Feng Zhang, Kai Liu +2
A recent experiment reported the first rare-earth binary oxide superconductor LaO ( 5 K) with a rock-salt structure [K. Kaminaga et al., J. Am. Chem. Soc. 140, 6754 (2…
Topological properties of MoC and WC superconductors
Ning-Ning Zhao, Peng-Jie Guo, Xiao-Qin Lu +3
The topological electronic properties of orthorhombic-phase MoC and WC superconductors have been studied based on first-principles electronic structure calculations. Ou…
Topological -wave superconductors driven by electron correlation
Huai-Shuang Zhu, Zhidan Li, Qiang Han +1
It is interesting to ask whether electron interaction can turn a topologically trivial superconductor into a nontrivial one without the presence of spin-obital coupling. In this pa…
Exact analysis on the singularity of the joint density of states and its relationship to the quasiparticle interference
Qiang Han, Dan-Bo Zhang, Z. D. Wang
Singularities of the joint density of states (JDOS) and Fourier-transformed local density of states (FT-LDOS) correspond to the hot spots in quasiparticle interference patterns. In…
Generalized joint density of states and its application to exploring the pairing symmetry of superconductors
Dan-Bo Zhang, Qiang Han, Z. D. Wang
We introduce a generalized joint density of states (GJDOS), which incorporates the coherent factor into the JDOS, to study quasiparticle interference (QPI) in superconductors. The…
Unconventional Fulde-Ferrel-Larkin-Ovchinnikov states in spin-orbit coupled condensates: exact results
Qiang Han, Jia Liu, Dan-Bo Zhang +1
We find that a model Hamiltonian of s-wave superconductors in the presence of spin-orbit interactions and a Zeeman field is exactly solvable. Most intriguingly, based on the exact…
