Quantum phase transition of correlated iron-based superconductivity in LiFeCoAs
Jia-Xin Yin, Songtian S. Zhang, Guangyang Dai +25
The interplay between unconventional Cooper pairing and quantum states associated with atomic scale defects is a frontier of research with many open questions. So far, only a few o…
Pairing in the Two-Dimensional Hubbard Model from Weak to Strong Coupling
Astrid T. Rømer, Thomas A. Maier, Andreas Kreisel +3
The Hubbard model is the simplest model that is believed to exhibit superconductivity arising from purely repulsive interactions, and has been extensively applied to explore a vari…
Visualization of local magnetic moments emerging from impurities in the Hund's metal states of FeSe
Sang Yong Song, J. H. J. Martiny, A. Kreisel +2
Understanding the origin of the magnetism of high temperature superconductors is crucial for establishing their unconventional pairing mechanism. Recently, theory predicts that FeS…
Anisotropic spin fluctuations in detwinned FeSe
Tong Chen, Youzhe Chen, Andreas Kreisel +15
Superconductivity in FeSe emerges from a nematic phase that breaks four-fold rotational symmetry in the iron plane. This phase may arise from orbital ordering, spin fluctuations, o…
Topological Ultranodal pair states in iron-based superconductors
Chandan Setty, Shinibali Bhattacharyya, Yifu Cao +2
Bogoliubov Fermi surfaces are contours of zero-energy excitations that are protected in the superconducting state. Here we show that multiband superconductors with dominant spin si…
