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…
Identification of soft modes across the commensurate-to-incommensurate charge density wave transition in 1-TaSe
M. Ruggeri, D. Wolverson, V. Romano +3
1-TaSe is a prototypical charge density wave (CDW) material for which electron-phonon coupling and associated lattice distortion play an important role in driving and stabil…
Resonance-Induced Anomalies in Temperature-Dependent Raman Scattering of PdSe
Omar Abdul-Aziz, Daniel Wolverson, Charles Sayers +4
We report a comprehensive Raman study of the phonon behaviour in PdSe in the temperature range of 5 K to 300 K. A remarkable change in the Raman spectrum is observed at 120 K:…
