Paramagnon softening upon doping in oxychloride cuprate superconductors
Chafic Fawaz, Léo Gaspard, Laura Chaix +15
Understanding how magnetic excitations and exchange interactions evolve with doping is crucial for deciphering the physics that shapes the phase diagram of high-temperature cuprate…
Raman scattering in cuprate oxychlorides high-temperature superconductors single-crystals
Chafic Fawaz, Yingzheng Gao, Luca Laveder +13
We investigate the Raman response of sodium-doped cuprate oxychloride NaCaCuOCl high-temperature superconductors across their entire phase diagram, from the…
Dynamics of surface electrons in a topological insulator: cyclotron resonance at room temperature
I. Mohelsky, F. Le Mardele, J. Dzian +13
The ability to manipulate the surface states of topological insulators using electric or magnetic fields under ambient conditions is a key step toward their integration into future…
Magneto-optical response of magnetic semiconductors EuCd2X2 (X= P, As, Sb)
S. Nasrallah, D. Santos-Cottin, F. Le Mardele +16
In this study, we identify EuCd2X2 (for X = P, As, Sb) as a series of magnetic semiconductors. We examine how the band gap of the series responds to X changing from phosphorus (P),…
Revealing the KH2PO4 soft-mode coupling mechanism with infrared spectroscopy under pressure
D. Santos-Cottin, S. Nasrallah, F. Capitani +4
We measured the far-infrared reflectivity of a KH2PO4 single crystal up to pressures of 2 GPa in the ferroelectric and paraelectric phases. We find that the nu4 vibrational mode of…
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…
