TL;DR: In this article, a spray pyrolysis technique has been employed successfully for the synthesis of single phase mixed valence spinel hausmannite thin films using alcoholic start solution of manganese acetate (Mn(CH3COO)2·4H2O) on pyrex glass substrates at atmospheric pressure using air as a carrier gas.

Abstract: Optical absorption of tris thiourea zinc sulphate (ZTS) single crystals has been measured and its direct band gap was found to be 3.6 eV. Theoretical calculations were carried out to determine the linear optical constants such as extinction coefficient and refractive index. Further the optical nonlinearties of ZTS have been investigated by Z-scan technique with He-Ne laser at 632.8 nm. The nonlinear refractive index, absorption coefficient and third order susceptibility is found to be in the order of –5.36 ± 0.26 × 10–12 cm2/W, 4.24 ± 0.21 × 10–4 cm/W, 3.5 ± 0.17 × 10–4 esu respectively. Thus optical characterization of ZTS reveals the various industrial application oriented properties of the material. (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

TL;DR: In this article, the collision dynamics of these coupled bright and dark solitons systematically were analyzed, and it was shown that for N>2, nontrivial effects, such as onset of intensity redistribution, amplitude-dependent phase shift, and change in relative separation distance take place in the bright solITons during collision.
Abstract: Mixed-type (bright-dark) soliton solutions of the integrable N-coupled nonlinear Schrodinger (CNLS) equations with mixed signs of focusing- and defocusing-type nonlinearity coefficients are obtained by using Hirota's bilinearization method. Generally, for the mixed N-CNLS equations the bright and dark solitons can be split up in (N-1) ways. By analyzing the collision dynamics of these coupled bright and dark solitons systematically we point out that for N>2, if the bright solitons appear in at least two components, nontrivial effects, such as onset of intensity redistribution, amplitude-dependent phase shift, and change in relative separation distance take place in the bright solitons during collision. However their counterparts, the dark solitons, undergo elastic collision but experience the same amplitude-dependent phase shift as that of bright solitons. Thus, in the mixed CNLS system, there is a coexisting shape-changing collision of bright solitons and elastic collision of dark solitons with amplitude-dependent phase shift, thereby influencing each other mutually in an intricate way.
