TL;DR: A snapshot of the present state of Surface Acoustic Wave science and technology in 2019 is presented and an opinion on the challenges and opportunities that the future holds is provided from a group of renown experts covering the interdisciplinary key areas.

TL;DR: In this article, the first experimental observations of bright polariton solitons in a strongly coupled semiconductor microcavity were made, and they were shown to be micrometre-scale localized non-diffracting wave packets with a corresponding broad spectrum in momentum space.

TL;DR: In this paper, the interaction between coherently stimulated acoustic phonons in the form of surface acoustic waves with light beams in semiconductor based photonic structures is reviewed and a detailed review of the physical and technological aspects related to control of the propagation and spatial distribution of the acoustic fields are discussed.

TL;DR: It is demonstrated that the tunable potential introduced by a surface acoustic wave on a homogeneous polariton condensates leads to fragmentation of the condensate into an array of wires which move with the acoustic velocity.

TL;DR: A new method for the coherent transport of spin-polarized electronic wave packets using dynamic quantum dots (DQDs) created by the piezoelectric field of coherent acoustic phonons is introduced.
