Nitesh and Hanna both pass their masters thesis defense and will soon start their PhDs in Germany and France.
Well done on some great work and good luck with the next step!

Nature Physics has published a Research Breifing article that summerize our recent paper on using transient correlated disorder to enhance the efficiency of photo-induced phase transitions. It also provides some "behind the scenes" motivation for the work and why the referees and editors found the paper interesting.

Our work on improving the energy efficiently of the light-induced phase transition in VO2 has now been published in Nature Physics.
We show that using two delayed femtosecond pulse can drive the phase transition with more efficiency than a signle femtosecond pulse. By measuring the time-resolved diffuse scattering signal in the low fluence regime, we show that this energy saving comes from the formation of non-thermal polarons which lower the barrier for the phase transition.

Our paper on using the change in reflectivity in materials resulting from coherent phonons as a tool for determining the spectral phase of a laser pulse has been published in Optics Express.
All data is open access and available from Zenodo

Our paper "Determination and correction of spectral phase from principal component analysis of coherent phonons" is now available as a pre-print on the arXiv.
In this work, we show a new method for determining the spectral phase of a probe pulse based on coherent phonon analysis that is useful for studying pulses used in experimental setups where direct diagnosis is not possible.
