Inter-orbital nematicity and the origin of a single electron Fermi pocket in FeSe
Daniel Steffensen, Andreas Kreisel, P. J. Hirschfeld +1
The electronic structure of the enigmatic iron-based superconductor FeSe has puzzled researchers since spectroscopic probes failed to observe the expected electron pocket at the $Y…
Orbital-dependent self-energy effects and consequences for the superconducting gap structure in multi-orbital correlated electron systems
Kristofer Björnson, Andreas Kreisel, Astrid T. Rømer +1
We perform a theoretical study of the effects of electronic correlations on the superconducting gap structure of multi-band superconductors. In particular, by comparing standard RP…
Singular magnetic anisotropy in the nematic phase of FeSe
R. Zhou, D. D. Scherer, H. Mayaffre +5
FeSe is arguably the simplest, yet the most enigmatic, iron-based superconductor. Its nematic but non-magnetic ground state is unprecedented in this class of materials and stands o…
On the Remarkable Superconductivity of FeSe and its Close Cousins
Andreas Kreisel, P. J. Hirschfeld, Brian M. Andersen
Emergent electronic phenomena in iron-based superconductors have been at the forefront of condensed matter physics for more than a decade. Much has been learned about the origin an…
Spatially dispersing Yu-Shiba-Rusinov states in the unconventional superconductor
Damianos Chatzopoulos, Doohee Cho, Koen M. Bastiaans +7
By using scanning tunneling microscopy (STM) we find and characterize dispersive, energy-symmetric in-gap states in the iron-based superconductor $\mathrm{FeTe}_{0.55}\mathrm{Se}_{…
Correlation-induced insulating topological phases at charge neutrality in twisted bilayer graphene
Yuan Da Liao, Jian Kang, Clara N. Breiø +5
Twisted bilayer graphene (TBG) provides a unique framework to elucidate the interplay between strong correlations and topological phenomena in two-dimensional systems. The existenc…
