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…
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…
