Magnetic Excitations in Strained Infinite-layer Nickelate PrNiO2
Qiang Gao, Shiyu Fan, Qisi Wang +16
Strongly correlated materials often respond sensitively to the external perturbations. In the recently discovered superconducting infinite-layer nickelates, the superconducting tra…
In-situ uniaxial pressure cell for X-ray and neutron scattering experiments
G. Simutis, A. Bollhalder, M. Zolliker +18
We present an in-situ uniaxial pressure device optimized for small angle X-ray and neutron scattering experiments at low-temperatures and high magnetic fields. A stepper motor gene…
Frustrated magnetic interactions in FeSe
Yiqing Gu, Qisi Wang, Hongliang Wo +7
The structurally simplest high-temperature superconductor FeSe exhibits an intriguing superconducting nematic paramagnetic phase with unusual spin excitation spectra that are diffe…
Pseudogap Suppression by Competition with Superconductivity in La-Based Cuprates
J. Küspert, R. Cohn Wagner, C. Lin +23
We have carried out a comprehensive high-resolution angle-resolved photoemission spectroscopy (ARPES) study of the pseudogap interplay with superconductivity in La-based cuprates.…
Anomalous contribution to the nematic electronic states from the structural transition in FeSe revealed by time- and angle-resolved photoemission spectroscopy
Yuanyuan Yang, Qisi Wang, Shaofeng Duan +8
High-resolution time- and angle-resolved photoemission measurements were made on FeSe superconductors. With ultrafast photoexcitation, two critical excitation fluences that corresp…
Fate of charge order in overdoped La-based cuprates
K. von Arx, Qisi Wang, S. Mustafi +18
In high-temperature cuprate superconductors, stripe order refers broadly to a coupled spin and charge modulation with a commensuration of eight and four lattice units, respectively…
