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…
Chiral excitations and the intermediate-field spin-liquid regime in the Kitaev magnet -RuCl
Anuja Sahasrabudhe, Mikhail A. Prosnikov, Thomas C. Koethe +6
In the Kitaev magnet -RuCl, the existence of a magnetic-field-induced quantum spin liquid phase and of anyonic excitations are discussed controversially. We address this elu…
RIXS interferometry and the role of disorder in the quantum magnet BaTiIrO
M. Magnaterra, M. Moretti Sala, G. Monaco +8
Motivated by several claims of spin-orbit driven spin-liquid physics in hexagonal BaTiIrO hosting Ir2O9 dimers, we report on resonant inelastic x-ray scattering…
Multiple Spin-Orbit Excitons and the Electronic Structure of -RuCl
P. Warzanowski, N. Borgwardt, K. Hopfer +7
The honeycomb compound -RuCl is widely discussed as a proximate Kitaev spin-liquid material. This scenario builds on spin-orbit entangled moments arising for a $t_…
Dynamics of incoherent exciton formation in CuO: Time- and angle-resolved photoemission spectroscopy
H. Tanimura, K. Tanimura, P. H. M. van Loosdrecht
We study dynamics of incoherent exciton formation under interband photoexcitation in CuO using time-and angle-resolved photoemission spectroscopy at 90 K. Hot electrons injecte…
