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…
Joint density of states and its relationship with quasiparticle interference pattern of d-wave superconductors
Qiang Han, Dan-Bo Zhang, Z. D. Wang
We present analytic analyses for the joint density of states (JDOS) and the elastic scattering susceptibility (ESS) for d-wave superconductors under the linear dispersion approxima…
