Our work of imaging the spatial dynamics of the insulator metal phase transition has been published in Nature Physics!
In this work, not only do we image dynamics of the phase transition with <50 nm spatial resolution and < 150 fs temporal resolution, but we also are able to perform spectroscopy on the transient state enabling us to identify differences between the light induced phase and the thermal phase.

Our work on the use of optical pulses to program neural networks in phase change materials is now published in nanophotonics.
The work was made in collaboration with Volker Sorger from George Washington University and Robert Simposon from the Singapore University of Technology and Design.

We have submitted our latest work on nanoscale imaging of the ultrafast phase transition in VO2 imaged using PAL-XFEL. Here we use spectroscopically resolved coherent diffractive imaging to observe local changes in the domain structure with <50 nm spatial resolution.

We have submitted a new pre-print on the photoinduced phase transition in V2O3. Here we show that the dynamics are governed by disorder and overdamping, rather than coherent motion, despite an ultrafast change in the potential symmetry.
