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…
Nonthermal order by disorder
Francesco Grandi, Antonio Picano, Ronny Thomale +2
The quench dynamics of systems exhibiting cooperative or almost competitive orders in equilibrium are explored using Ginzburg-Landau theory plus fluctuations. We show that when the…
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 from electronic correlations in CsTiBi kagome metal
Chiara Bigi, Matteo Dürrnagel, Lennart Klebl +19
Among many-body instabilities in correlated quantum systems, electronic nematicity, defined by the spontaneous breaking of rotational symmetry, has emerged as a critical phenomenon…
Probing chiral symmetry with a topological domain wall sensor
Glenn Wagner, Titus Neupert, Ronny Thomale +5
Chiral symmetry is a fundamental property with profound implications for the properties of elementary particles, that implies a spectral symmetry (i.e. E => -E ) in their dispersio…
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…
