Cooper Pairing and Phase Coherence in Iron Superconductor Fe1+x(Te,Se)
J. -X. Yin, Zheng Wu, X. Huang +14
The Cooper pairing and phase coherence are two fundamental aspects of superconductivity. Due to breaking time reversal symmetry, magnetic impurities are detrimental to superconduct…
Role of Arsenic in Iron-based Superconductivity at Atomic Scale
J. -X. Yin, Zheng Wu, X. X. Wu +15
In iron-based superconductors, a unique tri-layer Fe-As (Se, Te, P) plays an essential role in controlling the electronic properties, especially the Cooper pairing interaction. Her…
Orbital selectivity of layer resolved tunneling on iron superconductor Ba0.6K0.4Fe2As2
J. -X. Yin, X. -X. Wu, Jian Li +15
We use scanning tunneling microscopy/spectroscopy (STM/S) to elucidate the Cooper pairing of the iron pnictide superconductor Ba0.6K0.4Fe2As2. By a cold-cleaving technique, we obta…
Evolution of quasiparticle states with and without a Zn-impurity in doped 122 iron pnictides
Lihua Pan, Jian Li, Yuan-Yen Tai +3
Based on a minimal two-orbital model [Tai {\it et al.}, Europhys. Lett. \textbf{103}, 67001 (2013)], which captures the canonical electron-hole-doping phase diagram of the iron-pni…
Observation of a Robust Zero-energy Bound State in Iron-based Superconductor Fe(Te,Se)
J. -X. Yin, Zheng Wu, J. -H. Wang +14
A robust zero-energy bound state (ZBS) in a superconductor, such as a Majorana or Andreev bound state, is often a consequence of non-trivial topological or symmetry related propert…
Evolution of the Fermi surface topology in doped 122 iron pnictides
Lihua Pan, Jian Li, Yuan-Yen Tai +3
Based on the minimum two-orbital model and the phase diagram recently proposed by Tai et al.\ (Europhys. Lett. \textbf{103}, 67001(2013)) for both electron- and hole-doped 122 iron…
Interaction-induced localization of mobile impurities in ultracold systems
Jian Li, Jin An, C. S. Ting
The impurities, introduced intentionally or accidentally into certain materials, can significantly modify their characteristics or reveal their intrinsic physical properties, and t…
Magnetic domain walls induced by twin boundaries in low doped Fe-pnictides
Bo Li, Jian Li, Kevin E Bassler +1
Inspired by experimental observations of the enhancement of superconductivity at the twin-boundary (TB) in slightly electron doped Ba(Ca)(FeAs) where a strong antife…
Magnetic and superconducting structures near twin boundaries in low doped Fe-pnictides
Bo Li, Jian Li, Kevin E. Bassler +1
The effects of twin boundaries (TBs) on the complex interaction between magnetism and superconductivity in slightly electron-doped Ba(Ca)(FeAs) superconductors are investigated…
Interaction-induced localization of fermionic mobile impurities in a Larkin-Ovchinnikov superfluid
Jian Li, Jin An, C. S. Ting
We theoretically investigate the interplay between the fermionic mobile impurity atoms and a Larkin-Ovchinnikov (LO) superfluid in a two dimensional optical lattice. We find that t…
Pairing Symmetry in Iron-Pnictide Superconductor KFeAs
Wei Li, Jian Li, Jian-Xin Zhu +2
The pairing symmetry is one of the major issues in the study of iron-based superconductors. We adopt a low-energy effective kinetic model based on the first-principles band structu…
