Brillouin light scattering during shearing of complex fluids [PDF]
Optics Express, 2021 A setup for the optical measurement of elastic properties during the flow of complex fluids is presented. Brillouin light scattering and rotational rheology are combined in order to simultaneously measure the high-frequency longitudinal elastic modulus in a classical rheometer along with the zero-shear viscosity.

Brillouin scattering of phonons in complex materials [PDF]
Advances in Physics: X, 2018 Initially, the theory of propagation of long-wavelength acoustic phonons and Brillouin scattering of laser light in condensed matter is concisely summarized. Then, the case of two relevant classes of complex materials in which Brillouin scattering can be

Brillouin light-scattering from polymer gels [PDF]
Journal de Physique II, 1993 The experimental results of th Brillouin shift and width for poly(vinyl alcohol) and poly(vinyl chloride) gels as a function of gel network volume fraction have been analysed using the theory of Marqusee and Deutch for Brillouin light-scattering from polymer gels, incorporated with a new plausible assumption relating the speed of sound in the gel ...

Spin-orbit interaction through Brillouin scattering in nanofibers [PDF]
EPJ Web of Conferences, 2023 Spin-orbit interactions (SOI), describing the transfer of a spin degree of freedom to an orbital angular momentum (OAM), have been widely explored in recent opto-acoustic studies for applications mainly in spintronics and for topological insulators [1 ...

New approaches to extending the performance of Brillouin based slow light systems [PDF]
, 2007 We review the development of several new approaches for extending the performance of Brillouin based slow light systems. In particular we describe the use of cavity effects to enhance the achievable delays, gain saturation to decouple the delay and ...
