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…
Ultrafast X-ray imaging of the light-induced phase transition in VO2
Allan S. Johnson, Daniel Pérez-Salinas, Khalid M. Siddiqui +26
Using light to control transient phases in quantum materials is an emerging route to engineer new properties and functionality, with both thermal and non-thermal phases observed ou…
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…
Multi-mode excitation drives disorder during the ultrafast melting of a C4-symmetry-broken phase
Daniel Perez-Salinas, Allan S. Johnson, Dharmalingam Prabhakaran +1
Spontaneous C4-symmetry breaking phases are ubiquitous in layered quantum materials, and often compete with other phases such as superconductivity. Preferential suppression of the…
