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…
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…
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…
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…
Formation of Frustrated Charge Density Waves in Kagome Metal LuNbSn
F. Z. Yang, X. Huang, Hengxin Tan +14
The charge density wave (CDW), a translational symmetry breaking electronic liquid, plays a pivotal role in correlated quantum materials, such as high-T superconductors and top…
Field induced density wave in a kagome superconductor
Md Shafayat Hossain, Qi Zhang, Julian Ingham +19
On the kagome lattice, electrons benefit from the simultaneous presence of band topology, flat electronic bands, and van Hove singularities, forming competing or cooperating orders…
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…
Pomeranchuk Instability Induced by an Emergent Higher-Order van Hove Singularity on the Distorted Kagome Surface of CoSnS
Pranab Kumar Nag, Rajib Batabyal, Julian Ingham +11
Materials hosting flat bands at the vicinity of the Fermi level promote exotic symmetry broken states. Common to many of these are van Hove singularities at saddle points of the di…
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…
Van-Hove annihilation and nematic instability on a Kagome lattice
Yu-Xiao Jiang, Sen Shao, Wei Xia +20
Novel states of matter arise in quantum materials due to strong interactions among electrons. A nematic phase breaks the point group symmetry of the crystal lattice and is known to…
