    Notes: One-dimensional three-wave models, known for stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS), are investigated. It is shown that in homogeneous systems of infinite extent the steady-state three-wave solution for SBS with a reflectivity less than 100% is intrinsically unstable. From a numerical solution it is concluded that nearly all stationary states decay in time and result in a state with reflectivity coefficient R=1; only the latter is linearly stable in a homogeneous plasma of infinite length. The asymptotic solutions for SBS in plasmas are calculated and the similarity in the dynamics between SBS and SRS is discussed.

    Description: Defect engineering is an effective and powerful tool to control the existing material properties and produce completely new ones, which are symmetry-forbidden in a defect-free crystal. For example, the application of a static electric field to a single crystal of SrTiO 3 forms a strained near-surface layer through the migration of oxygen vacancies out of the area beneath the positively charged electrode. While it was previously shown that this near-surface phase holds pyroelectric properties, which are symmetry-forbidden in centrosymmetric bulk SrTiO 3 , this paper reports that the same phase is strongly piezoelectric. We demonstrate the piezoelectricity of this phase through stroboscopic time-resolved X-ray diffraction under alternating electric field and show that the effective piezoelectric coefficient d 33 ranges between 60 and 100 pC/N. The possible atomistic origins of the piezoelectric activity are discussed as a coupling between the electrostrictive effect and spontaneous polarization of this near-surface phase.
