Tracking the Catastrophic Collapse of Hybrid Exciton-Phonon Order in a Quantum Material
Omar Abdul-Aziz, Danilo Comini, Johannes Lang +8
Revealing the interactions binding electronic and lattice components of cooperative quantum order is central to sculpting new states of matter. This challenge is epitomized by the…

Photoinduced Electronic Band Dynamics and Defect-mediated Surface Potential Evolution in PdSe
Omar Abdul-Aziz, Manuel Tuniz, Wibke Bronsch +9
We use time- and angle-resolved photoemission spectroscopy (TR-ARPES) combined with density functional theory to investigate ultrafast carrier dynamics in low-symmetry layered semi…

Quasimolecular electronic structure of the trimer iridate BaNbIrO
M. Magnaterra, A. Sandberg, H. Schilling +17
The insulating mixed-valent Ir compound BaNbIrO hosts two holes per IrO trimer unit. We address the electronic structure via resonant inelastic…
