Thermodynamics of the ultrafast phase transition of vanadium dioxide
Shreya Bagchi, Ernest Pastor, José Santiso +2
Ultrafast photoexcitation is an emerging route to selective control of phase transitions. However, it is difficult to determine which modes govern the transformation and how effect…

Determination and correction of spectral phase from principal component analysis of coherent phonons
Emmanuel B. Amuah, Khalid M. Siddiqui, Maurizio Monti +2
Measuring the spectral phase of a pulse is key for performing wavelength resolved ultrafast measurements in the few femtosecond regime. However, accurate measurements in real exper…

All-optical seeding of a light-induced phase transition with correlated disorder
Allan S. Johnson, Ernest Pastor, Sergi Batlle-Porro +8
Ultrafast manipulation of vibrational coherence is an emergent route to control the structure of solids. However, this strategy can only induce long-range correlations and cannot m…
