Collective Excitations in High-Temperature Superconductors

, 1997
Collective, low-energy excitations in quasi-two-dimensional d-wave superconductors are analyzed. While the long-range Coulomb interaction shifts the charge-density-wave and phase modes up to the plasma energy, the spin-density-wave excitation that arises

Theorical and descriptive analysis of the wave energy in the Barcelona World Race [PDF]

, 2014
The main objective of this paper is the presentation of a theoretical study of the wave energy in some zones of the Barcelona World Race (BWR) considering different theories, how much of this energy is transferred to the boat and if it is possible to use

Localized and Extended States in One-Dimensional Disordered System: Random-Mass Dirac Fermions

, 1999
System of Dirac fermions with random-varying mass is studied in detail. We reformulate the system by transfer-matrix formalism. Eigenvalues and wave functions are obtained numerically for various configurations of random telegraphic mass m(x ...

Determination of the right wave by empirical statistics: The wave energy resource assessment and the investigation of existing marine and coastal potential compatibility

Journal of Ocean Engineering and Science, 2016
In competition with other resources, ocean waves provide abundant supply of clean, safe, and reliable energy, but this source needs to be made an economical source for natural energy harvest. For this purpose, a wave energy conversion device is developed

Confined states in two-dimensional flat elliptic quantum dots and elliptic quantum wires

, 2001
The energy spectrum and corresponding wave functions of a flat quantum dot with elliptic symmetry are obtained exactly. A detailed study is made of the effect of ellipticity on the energy levels and the corresponding wave functions.
