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…
Loop Current Order on the Kagome Lattice
Jun Zhan, Hendrik Hohmann, Matteo Dürrnagel +6
Recent discoveries in kagome materials have unveiled their capacity to harbor exotic quantum states, including intriguing charge density wave (CDW) and superconductivity. Notably,…
Kekulé order from diffuse nesting near higher-order Van Hove points
Jonas Beck, Jonathan Bodky, Matteo Dürrnagel +4
Translation symmetry-breaking order is assumed to be suppressed by the lack of Fermi surface nesting near certain higher-order Van Hove singularities (HOVHS). We show the anisotrop…
Altermagnetic phase transition in a Lieb metal
Matteo Dürrnagel, Hendrik Hohmann, Atanu Maity +4
We analyze the phase transition between a symmetric metallic parent state and itinerant altermagnetic order. The underlying mechanism we reveal in our microscopic model of electron…
Theory of unconventional magnetism in a Cu-based kagome metal
Anja Wenger, Armando Consiglio, Hendrik Hohmann +6
Kagome metals have established a new arena for correlated electron physics. To date, the predominant experimental evidence centers around unconventional charge order, nematicity, a…
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…
Exotic charge density waves and superconductivity on the Kagome Lattice
Rui-Qing Fu, Jun Zhan, Matteo Dürrnagel +6
Recent experiments have identified fascinating electronic orders in kagome materials, including intriguing superconductivity, charge density wave (CDW) and nematicity. In particula…
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…
Observation of cnoidal wave localization in non-linear topolectric circuits
Hendrik Hohmann, Tobias Hofmann, Tobias Helbig +12
We observe a localized cnoidal (LCn) state in an electric circuit network. Its formation derives from the interplay of non-linearity and the topology inherent to a Su-Schrieffer-He…
