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…
A versatile setup for symmetry-resolved ultrafast dynamics of quantum materials
Khalid M. Siddiqui, Hanna Strojecka, Thomas H. Meyland +4
Correlated phenomena occur in quantum materials because of the delicate interplay between internal degrees of freedom, leading to multiple symmetry-broken quantum phases. Resolving…
Ultrafast surface melting of orbital order in La0.5Sr1.5MnO4
Maurizio Monti, Khalid M. Siddiqui, Daniel Perez-Salinas +12
Understanding how light modifies long-range order in quantum materials is key to improving our ability to control functionality. However, this is challenging if the response is het…
Electron coherent phonon coupling in PrCaMnO measured with ultrafast broadband spectroscopy
Emmanuel B. Amuah, Khalid M. Siddiqui, Maurizio Monti +5
Photoexcitation of single-layered LaMnMnO has played a key role in understanding orbital ordering and non-thermal states in the manganites. However, while orbit…
