Chiral charge density waves in transition metal dichalcogenide
Ettore Carpene
The emergence of chirality in the charge density wave (CDW) phase of 1-TiSe has recently attracted significant attention, yet its microscopic origin remains debated. The pre…
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…
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:…
Ultrafast Evolution of Bulk, Surface and Surface Resonance States in Photoexcited BiTe
Hamoon Hedayat, Davide Bugini, Hemian Yi +5
We use circular dichroism (CD) in time- and angle-resolved photoemission spectroscopy (trARPES) to measure the femtosecond charge dynamics in the topological insulator (TI) Bi$_{2}…
Coherent ultrafast spin-dynamics probed in three dimensional topological insulators
F. Boschini, M. Mansurova, G. Mussler +12
Topological insulators are candidates to open up a novel route in spin based electronics. Different to traditional ferromagnetic materials, where the carrier spin-polarization and…
