The superconducting compound BaCaLaCu 3 O y , T c ∼80 K, can accommodate the gradual replacement of Ca by Cd and systematically have its transition temperature lowered. Previous experiments showed that when either Zn or Cd was used to replace one o

The system La 3 Ba 3 Ca x Cu 6+ x O y was chosen for a study as a system on high temperature superconductors. The system retains its tetragonal triple layer perovskite structure over the range 0≤ x ≤3. The transition temperature ( T c ) defined b

The coupled electron-phonon system is considered for phonon spectra of Einstein and Debye forms. The single-particle electron Green's function $G$ is calculated in a nonperturbative manner in both models, and its spectral weight function is examined

The spectrum of uncorrelated temperature fluctuations in a steady state is proposed using concepts of local equilibrium and microscopic reversibility of temperature fluctuations. Two one-dimensional examples show that as long as the linearity of the

The properties of a one-dimensional system of degenerate electrons coupled to long-wavelength phonons are investigated. The equivalent model Hamiltonian of Tomonaga, which describes the electrons by density waves, is diagonalized to normal modes. The

The relation which exists between the Coulomb energy losses of an electron passing through a crystal and the absorption of light by the same crystal is examined in the Born approximation. It is found that at long wavelengths the validity of the Born

The thermodynamic potential and magnetization are calculated for a system of electrons interacting with phonons in the presence of a magnetic field. The results are used for a numerical evaluation of the de Haas-van Alphen amplitude of the oscillatio
