Metallic layered materials with magnetic frustration: An ARPES view of the SmAuAlGe and TbAuAlGe

P. Rezende-Gonçalves, A. Antezak, T. Kato +10

Compounds of the new materials class LnTAlX (Ln = lanthanide, X = tetrel, T = transition metal) host exotic magnetic phenomena due to geometric frustration induced by their…

Electronic structure dimensionality of the quantum-critical ferromagnet YbNiP

J. Dai, A. Antezak, W. Broad +15

YbNiP is the first known ferromagnetic metal showing a second-order quantum phase transition. Current theoretical understanding rules out second order ferromagnetic quantum…

Anomalous spin-optical helical effect in Ti-based kagome metal

Federico Mazzola, Wojciech Brzezicki, Chiara Bigi +32

The kagome lattice stands as a rich platform for hosting a wide array of correlated quantum phenomena, ranging from charge density waves and superconductivity to electron nematicit…

On the cuprates' universal waterfall feature: evidence of a momentum-driven crossover

Benjamin Bacq-Labreuil, Chafic Fawaz, Yuichi Okazaki +13

We study two related universal anomalies of the spectral function of cuprates, so called waterfall and high-energy kink features, by a combined cellular dynamical mean-field theory…

Bilayer orthogonal ferromagnetism in CrTe-based van der Waals system

Chiara Bigi, Cyriack Jego, Vincent Polewczyk +19

Systems with pronounced spin anisotropy play a pivotal role in advancing magnetization switching and spin-wave generation mechanisms, which are fundamental for spintronic technolog…

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…
