Ultrafast lattice disordering can be accelerated by electronic collisional forces
Gilberto A. de la Pena Munoz, Alfredo A. Correa, Shan Yang +11
In the prevalent picture of ultrafast structural phase transitions, the atomic motion occurs in a slowly varying potential energy surface determined adiabatically by the fast elect…
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…
Dynamics of electronic states in the insulating Intermediate surface phase of 1T-TaS
Jingwei Dong, Weiyan Qi, Dongbin Shin +14
This article reports a comparative study of bulk and surface properties in the transition metal dichalcogenide 1T-TaS. When heating the sample, the surface displays an intermed…
Correlating activity and defects in (photo)electrocatalysts using in-situ transient optical microscopy
Camilo A. Mesa, Michael Sachs, Ernest Pastor +8
(Photo)electrocatalysts capture sunlight and use it to drive chemical reactions such as water splitting to produce H2. A major factor limiting photocatalyst development is their la…
Electronic dispersion, correlations and stacking in the photoexcited state of 1T-TaS
Jingwei Dong, Dongbin Shin, Ernest Pastor +11
Here we perform angle and time-resolved photoelectron spectroscopy on the commensurate Charge Density Wave (CDW) phase of 1T-TaS. Data with different probe pulse polarization a…
Electronic Defects in Metal Oxide Photocatalysts
Ernest Pastor, Michael Sachs, Shababa Selim +3
A deep understanding of defects is essential for the optimisation of materials for solar energy conversion. This is particularly true for metal oxide photo(electro)catalysts, which…
Ultrafast loss of lattice coherence in the light-induced structural phase transition of VO
A. S. Johnson, D. Moreno-Mencía, E. B. Amuah +5
In solids, the response of the lattice to photo-excitation is often described by the inertial evolution on an impulsively modified potential energy surface which leads to coherent…
Non-thermal breaking of magnetic order via photo-generated spin defects
Ernest Pastor, David Moreno-Mencía, Maurizio Monti +8
In Mott insulators the evolution of antiferromagnetic order to superconducting or charge-density-wave-like states upon chemical doping underpins the control of quantum phases. Phot…
All-Chalcogenide Programmable All-Optical Deep Neural Networks
Ting Yu, Xiaoxuan Ma, Ernest Pastor +5
Deeplearning algorithms are revolutionising many aspects of modern life. Typically, they are implemented in CMOS-based hardware with severely limited memory access times and ineffi…
