Subterahertz collective dynamics of polar vortices
Qian Li, Vladimir A. Stoica, Marek Paściak +29
The collective dynamics of topological structures have been of great interest from both fundamental and applied perspectives. For example, the studies of dynamical properties of ma…
Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
Dynamical slowing down in an ultrafast photo-induced phase transition
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +20
Complex systems, which consist of a large number of interacting constituents, often exhibit universal behavior near a phase transition. A slowdown of certain dynamical observables…
