TL;DR: In this paper, the authors investigated the thermal relaxation of a spatially sinusoidal temperature perturbation in a dielectric crystal at a temperature comparable to or higher than the Debye temperature.

TL;DR: In this article, the interaction of surface acoustic waves (SAWs) with the contact-based, axial vibrational resonance of 1 μm silica microspheres forming a two-dimensional granular crystal adhered to a substrate was studied.

TL;DR: The merits of existing single-shot THz schemes are reviewed and their potential in multidimensional THz spectroscopy is discussed, and improved experimental designs and noise suppression techniques are introduced for the two most promising methods: frequency- to-time encoding with linear spectral interferometry and angle-to- time encoding with dual echelons.

TL;DR: In this article, the effects of absorption losses in photonic crystal structures composed of polar materials which exhibit transverse phonon-polariton excitations were examined, and two subspaces of the complete set of complex (k,v) states consisting of either real frequency, accessible through a frequency-domain method, or real-wave vector, which were determined using a frequencydependent time-domain approach.

TL;DR: In this paper, temperature-dependent molecular dynamics of CS 2 liquid were examined in femtosecond time-resolved impulsive stimulated scattering experiments, where weakly oscillatory time-dependent responses were observed.
