Superconductivity: Properties, Applications and New Developments

ISBN: 9781634839570 出版年：2015 页码：186 Paulette Grant Nova Science

This book presents research on superconductivity. The first chapter discusses the physical properties of two nonmagnetic noncentrosymmetric superconductors, LaRhSi3 and LaIrSi3. Chapter two reviews the SrFe2As2 and FeTe0.8S0.2 compounds, which are perspective for developing new superconducting materials on their basis. The possibility of selective excitation of the nonlinear lattice vibrations in high-temperature superconductors formed from layers or thin films opens the new perspectives in the manipulations and control of quantum field in superconducting phase, which is further discussed in chapter three. Chapter four begins with a detailed derivation of the three coupled integral equations associated with the so-called generalized Bose-Einstein condensation formalism of a many-fermion system. Finally, chapter five proposes a microscopic theory of superconductivity based on the spinfluctuation mechanism of pairing.
