Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
Dongjin Oh, Stefan Enzner, Lennart Klebl +12
The kagome superconductor family AV3Sb5 (A=Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various…
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…
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…
Group theory method for extracting order parameters from scanning tunneling microscopy data
Julian Ingham, Yu-Xiao Jiang, M. Zahid Hasan +1
Scanning tunneling microscopy (STM) is a powerful local probe of correlated electronic states. Here we present a group theoretical framework for the analysis of STM data, filtering…
Theory of excitonic order in kagome metals ScVSn and LuNbSn
Julian Ingham, Armando Consiglio, Domenico di Sante +2
We argue that kagome metals can feature an excitonic condensate of unconventional nature. Studying the recently discovered variants ScVSn and LuNbSn we identify ele…
Vestigial Order from an Excitonic Mother State in Kagome Superconductors VSb
Julian Ingham, Ronny Thomale, Harley D. Scammell
Alongside high-temperature charge order and superconductivity, kagome metals exhibit signatures of time-reversal symmetry breaking and nematicity which appear to depend strongly on…
