Pair density wave order from non-symmorphic momentum symmetry
Matteo Dürrnagel, C. Alexander Baum, Michael Klett +2
We develop a class of microscopic lattice models in which pair density wave order emerges in the asymptotically exact weak coupling limit. The underlying mechanism is due to non-sy…
Exotic Electronic Order in a Parabolic Kagome Semimetal
C. Alexander Baum, Jonas Issing, Sarbajit Mazumdar +4
We study an interacting kagome-lattice realization of a quadratic band-touching semimetal at 2/3 filling with onsite and nearest-neighbor repulsive interactions. Combining function…
Phase-sensitive evidence for pair density waves in a kagome superconductor
Xiao-Yu Yan, Guowei Liu, Hanbin Deng +22
Pair density wave (PDW) exhibits periodic amplitude and sign modulations of the superconducting order parameter. Such a pairing state has long been proposed to be highly sensitive…
Moiré-resonant surface state in ultrathin RuO
Philipp Keßler, Andreas Feuerpfeil, Armando Consiglio +9
RuO has emerged as a prototypical candidate for altermagnetism. In the face of daunting evidence for magnetic order in the bulk, the focus naturally shifted to surfaces and ult…
Chiral kagome superconductivity modulations with residual Fermi arcs in KV3Sb5 and CsV3Sb5
Hanbin Deng, Hailang Qin, Guowei Liu +26
Superconductivity involving finite momentum pairing can lead to spatial gap and pair density modulations, as well as Bogoliubov Fermi states within the superconducting gap. However…

The kagome Hubbard model from a functional renormalization group perspective
Jonas B. Profe, Lennart Klebl, Francesco Grandi +5
The recent discovery of a variety of intricate electronic order in kagome metals has sprouted significant theoretical and experimental interest. From an electronic perspective on t…
Van-Hove tuning of Fermi surface instabilities through compensated metallicity
Hendrik Hohmann, Matteo Dürrnagel, Matthew Bunney +6
Van-Hove (vH) singularities in the vicinity of the Fermi level facilitate the emergence of electronically mediated Fermi surface instabilities. This is because they provide a momen…
Sublattice modulated superconductivity in the Kagome Hubbard model
Tilman Schwemmer, Hendrik Hohmann, Matteo Dürrnagel +8
We identify a superconducting order featuring spatial pair modulations on the kagome lattice subject to onsite Hubbard U and nearest neighbor V interactions. Within our functional…
Hybrid s-wave superconductivity in CrB
Sananda Biswas, Andreas Kreisel, Adrian Valadkhani +5
In a metal with multiple Fermi pockets, the formation of s-wave superconductivity can be conventional due to electron-phonon coupling or unconventional due to spin fluctuations. We…
