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…
Anomalous amplitude mode dynamics below the expected charge-density-wave transition in 1-VSe
Charles J. Sayers, Giovanni Marini, Matteo Calandra +6
A charge-density-wave (CDW) is characterized by a dynamical order parameter consisting of a time-dependent amplitude and phase, which manifest as optically-active collective modes…
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:…
