Emergent Antiphase Stacking in a Transient Charge Density Wave
Jade Stanton, Gal Orenstein, Ryan A. Duncan +14
Photoexcitation can induce novel states in materials that are inaccessible in equilibrium, a recent example being the light-induced charge density wave (CDW) observed in $\text{LaT…
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…
Ultrafast measurements under anisotropic strain reveal near equivalence of competing charge orders in TbTe
Soyeun Kim, Gal Orenstein, Anisha G. Singh +3
We report ultrafast reflectivity measurements of the dynamics of the order parameter of the charge density wave (CDW) in TbTe under anisotropic strain. We observe an increase i…
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…
Observation of the massive Lee-Fukuyama phason in a charge density wave insulator
Soyeun Kim, Yinchuan Lv, Xiao-Qi Sun +10
The lowest-lying fundamental excitation of an incommensurate charge density wave (CDW) material is widely believed to be a massless phason -- a collective modulation of the phase o…
Formation of buried domain walls in the ultrafast transition of SmTe
M. Trigo, P. Giraldo-Gallo, J. N. Clark +13
We study ultrafast x-ray diffraction on the charge density wave (CDW) of SmTe using an x-ray free electron laser. The CDW peaks show that photoexcitation with near-infrared pum…
