Witnessing Quantum Entanglement Using Resonant Inelastic X-ray Scattering
Tianhao Ren, Yao Shen, Marton Lajer +9
Although entanglement is both a central ingredient in our understanding of quantum many-body systems and an essential resource for quantum technologies, we only have a limited abil…
Superconducting phase diagram of multi-layer square-planar nickelates
Grace A. Pan, Dan Ferenc Segedin, Sophia F. R. TenHuisen +21
The discovery of superconductivity in square-planar nickelates has offered a rich materials platform to explore the origins of cuprate-like superconductivity. Experimental investig…
Electronic layer decoupling driven by density-wave order in LaNiO
Ziqiang Guan, Sophia F. R. TenHuisen, M. Tepie +14
We probe the density-wave transition of the trilayer nickelate LaNiO with polarization-resolved infrared spectroscopy. The low-energy electrodynamics is strongly ani…
A light-induced charge order mode in a metastable cuprate ladder
Hari Padma, Prakash Sharma, Sophia F. R. TenHuisen +17
We report the observation of an emergent charge order mode in the optically-excited cuprate ladder SrCuO. Near-infrared light in the ladder plane drives a symm…
Symmetry-protected electronic metastability in an optically driven cuprate ladder
Hari Padma, Filippo Glerean, Sophia F. R. TenHuisen +23
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
