Supercurrent effect in a charge density wave intertwined superconductor
Zhen Zhu, Wei Cheng, Dang Liu +15
The energy-momentum (E-k) dispersion of quasiparticles constitutes a fundamental concept in condensed matter systems. The ability to modify the E-k dispersion, exemplified by super…
Quantum-size effect induced Andreev bound states in ultrathin metallic islands proximitized by a superconductor
Guanyong Wang, Li-Shuo Liu, Zhen Zhu +9
While Andreev bound states (ABSs) have been realized in engineered superconducting junctions, their direct observation in normal metal/superconductor heterostructures-enabled by qu…
Discovery of segmented Fermi surface induced by Cooper pair momentum
Zhen Zhu, Michał Papaj, Xiao-Ang Nie +12
Since the early days of Bardeen-Cooper-Schrieffer theory, it has been predicted that a sufficiently large supercurrent can close the energy gap in a superconductor and creates gapl…
Observation of Majorana fermions with spin selective Andreev reflection in the vortex of topological superconductor
Hao-Hua Sun, Kai-Wen Zhang, Lun-Hui Hu +14
Majorana fermion (MF) whose antiparticle is itself has been predicted in condensed matter systems. Signatures of the MFs have been reported as zero energy modes in various systems.…
Electronic structure of a superconducting topological insulator Sr-doped Bi2Se3
C. Q. Han, H. Li, W. J. Chen +10
Using high-resolution angle-resolved photoemission spectroscopy and scanning tunneling microscopy/spectroscopy, the atomic and low energy electronic structure of the Sr-doped super…
Fully Gapped s-wave-like Superconducting State and Electronic Structures in the Ir0.95Pd0.05Te2 Single Crystals with Strong Spin-orbital Coupling
D. J. Yu, F. Yang, Lin Miao +15
Due to the large spin-orbital coupling in the layered 5d-transition metal chalcogenides compound, the occurrence of superconductivity in Ir2-xPdxTe2 offers a good chance to search…
