Emergent Antiphase Stacking in a Transient Charge Density Wave

Jade Stanton, Gal Orenstein, Ryan A. Duncan, Gilberto A. de la Peña Muñoz et autres

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 $\text{LaTe}_3$. Here, we investigate this transient CDW using infrared-pump x-ray-probe scattering at a free-electron laser, with high momentum …

Dynamical Scaling Reveals Topological Defects and Anomalous Evolution of a Photoinduced Phase Transition

Gal Orenstein, Ryan A. Duncan, Gilberto A. de la Peña Muñoz, Yijing Huang et autres

Nonequilibrium states of quantum materials can exhibit exotic properties and enable unprecedented functionality and applications. These transient states are inherently inhomogeneous, characterized by the formation of topologically protected structures, requiring nanometer spatial resolution on femtosecond timescales to resolve their evolution. Using ultrafast …

All-optical seeding of a light-induced phase transition with correlated disorder

Allan S. Johnson, Ernest Pastor, Sergi Batlle-Porro, H. Benzidi et autres

Ultrafast manipulation of vibrational coherence provides a route to control the structure of solids. However, this strategy can only induce long-range correlations and cannot modify atomic structure locally, which is a requirement for many technological applications such as non-volatile electronics. Here we …

All-optical seeding of a light-induced phase transition with correlated disorder

Allan S. Johnson, Ernest Pastor, Sergi Batlle-Porro, H. Benzidi et autres

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 modify atomic structure locally, which is required in many technologically-relevant phase transitions. Here, we demonstrate that ultrafast …

Ultrafast lattice disordering can be accelerated by electronic collisional forces

Gilberto A. de la Peña Muñoz, Alfredo A. Correa, Shan Yang, Olivier A. Delaire et autres

In the prevalent picture of ultrafast structural phase transitions, atomic motion occurs in a slowly varying potential energy surface adiabatically determined by fast electrons. However, this ignores non-conservative forces caused by electron–lattice collisions, which can substantially influence atomic motion. Most ultrafast techniques …
