Ultrafast transient increase of oxygen octahedral rotations in a perovskite
M. Porer, M. Fechner, M. Kubli +13
The ability to control the structure of a crystalline solid on ultrafast timescales bears enormous potential for information storage and manipulation or generating new functional s…

Ultrafast x-ray diffraction probe of terahertz field-driven soft mode dynamics
M. Kozina, T. van Driel, M. Chollet +6
We use ultrafast x-ray pulses to characterize the lattice response of SrTiO3 when driven by strong terahertz (THz) fields. We observe transient changes in the diffraction intensity…
