High-resolution three-dimensional imaging of topological textures in single-diamond networks

Kavli Affiliate: Ulrich B. Wiesner | First 5 Authors: Dmitry Karpov, Kenza Djeghdi, Mirko Holler, S. Narjes Abdollahi, Karolina Godlewska | Summary: Highly periodic structures are often said to convey the beauty of nature. However, most material properties are strongly influenced by the defects they contain. On the mesoscopic scale, molecular self-assembly exemplifies this interplay; […]

Coherent control of the translational and point group symmetries of crystals with light

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Guru Khalsa, Jeffrey Z. Kaaret, Nicole A. Benedek, , | Summary: We use theory and first-principles calculations to explore mechanisms for control of the translational and point group symmetries of crystals in ultrafast optical experiments. We focus in particular on mechanisms that exploit anharmonic (biquadratic) lattice […]
