TL;DR: In this article, the authors studied the effect of contact-based and sphere-sphere contacts on spheroidal vibrational modes of the spheres within a perturbative approach.

TL;DR: These TDBS results reveal that confinement effects favor structuring of the smectic phase into a crystallinelike phase that can be observed at wide distances far beyond the molecular dimensions.

TL;DR: In this paper, single-shot multi-frame imaging of quasi-2D cylindrically converging shock waves as they propagate through a multi-layer target sample assembly is presented.

TL;DR: In this paper, the photochromic intramolecular proton transfer in 2-(2′,4′-dinitrobenzyl)pyridine was investigated by femtosecond pump-probe transient absorption spectroscopy.

TL;DR: It is observed that the THz pump pulse causes a selective modification of the coherence lifetime of the excitons, while keeping their oscillator strength and peak energy unchanged, which opens the way to the use of semiconducting transition metal dichalcogenides as compact and efficient platforms for high-speed electroabsorption devices.
