X-ray Thermal diffuse scattering from real-space displacement correlations
Benjamin Fahl, Jonathan Bulled, Artem Korshunov +3
We introduce a method for calculating X-ray thermal diffuse scattering based on the three-dimensional difference pair distribution function (3D-dPDF). Within the harmonic approxima…
Disentangling pre-transitional fluctuations in metallic VO2
Javier del Valle, Carl Willem Rischau, Artem Korshunov +8
VO2 features concomitant structural and metal-insulator transitions. This poses a challenge for understanding the underlying mechanism: is the transition triggered by a structural…
Self-stacked 1-1 layers in 6-NbSeTe and the emergence of charge and magnetic correlations due to ligand disorder
S. K. Mahatha, J. Phillips, J. Corral-Sertal +14
The emergence of correlated phenomena arising from the combination of 1 and 1 van der Waals layers is the focus of intense research. Here, we synthesize a n…
Anomalous T-dependence of phonon lifetimes in metallic VO2
Carl Willem Rischau, Artem Korshunov, Volodymyr Multian +9
We investigate phonon lifetimes in VO2 single crystals. We do so in the metallic state above the metal-insulator transition (MIT), where strong structural fluctuations are known to…
