Temperature-dependent phonon spectra of magnetic random solid solutions

PHONON SPECTRA OF HIGH TEMPERATURE SUPERCONDUCTOR Bi2Sr2Ca2Cu3O10 : THEORY AND EXPERIMENT*

Since the discovery of the high Tc superconductivity by Bednorz and Muller, several workers around the world have studied several systems to reach a really high Tc superconductor. As the strong electron-phonon coupling may be one of the possible origins of the high Tc, a knowledge about the phonon in these materials is essential. In order to investigate phonon spectra, Raman and infrared spectr...

Temperature dependent phonon renormalization in metallic nanotubes

Raman spectroscopy is a powerful non destructive technique for the characterization of carbon materials, and is a fundamental tool in the recent advances in the understanding of single wall carbon nanotubes (SWNTs). Raman experiments probe the optical phonons, allowing to assess the vibrational properties of the analyzed materials. A strong interplay exists between temperature (T ) and phonon f...

Dependent Lattice Random Elements

In this study, we first introduce the Banach lattice random elements and some of their properties. Then, using the order defined in Banach lattice space, we introduce and characterize the order negatively dependence Banach lattice random elements by the order defined in Banach lattice space. Finally, we obtain some limit theorems for the sequence of order negatively dependence Banach lattice ra...
