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…
Paramagnon dispersion and damping in doped NaCaCuOCl
Blair W. Lebert, Benjamin Bacq-Labreuil, Mark P. M. Dean +13
Using Resonant Inelastic X-ray Scattering, we measure the paramagnon dispersion and damping of undoped, antiferromagnetic CaCuOCl as well as doped, superconducting Na$_…
Two-dimensional fluctuations and competing phases in the stripe-like antiferromagnet BaCoS
Haneen Abushammala, Benjamin Lenz, Benoit Baptiste +5
By means of a combined x-ray diffraction, magnetic susceptibility and specific heat study, we investigate the interplay between orthorhombic distortion and stripe-like antiferromag…
Evidence of 3D Dirac conical bands in TlBiSSe by optical and magneto-optical spectroscopy
F. Le Mardelé, J. Wyzula, I. Mohelsky +15
TlBiSSe is a rare realization of a 3D semimetal with a conically dispersing band that has an optical response which is well isolated from other contributions in a broad range of ph…
EuCdAs: a magnetic semiconductor
D. Santos-Cottin, I. Mohelský, J. Wyzula +18
EuCdAs is now widely accepted as a topological semimetal in which a Weyl phase is induced by an external magnetic field. We challenge this view through firm experimental ev…
