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…
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…
Tunable valley Hall effect in gate-defined graphene superlattices
Johannes H. J. Martiny, Kristen Kaasbjerg, Antti-Pekka Jauho
We theoretically investigate gate-defined graphene superlattices with broken inversion symmetry as a platform for realizing tunable valley dependent transport. Our analysis is moti…
Theoretical study of impurity-induced magnetism in FeSe
Johannes H. J. Martiny, Andreas Kreisel, Brian M. Andersen
Experimental evidence suggests that FeSe is close to a magnetic instability, and recent scanning tunneling microscopy (STM) measurements on FeSe multilayer films have revealed stri…
Symmetry-forbidden intervalley scattering by atomic defects in monolayer transition-metal dichalcogenides
Kristen Kaasbjerg, Johannes H. J. Martiny, Tony Low +1
Intervalley scattering by atomic defects in monolayer transition metal dichalcogenides (TDMs; MX2) presents a serious obstacle for applications exploiting their unique valley-contr…
