  title={Coalescence of Impurity Strontium Atoms in Lightly-Substituted Samples of Lanthanum Cuprate},
  author={E. Yu. Beliayev and Dianela Osorio and Pedro L. Contreras E.},
: By comparing experimental results obtained in the study of the electron transport and magnetic properties of samples of lightly strontium-substituted lanthanum cuprates and the results of a previously published numerical analysis in the reduced elastic scattering space (RPS) of the elastic scattering cross-section, we construct a phenomenological classical self-consistent strong-binding energy density profile in the superconducting La 2-x Sr x CuO 4 cuprate. It is found that the imaginary…

Tight-Binding Superconducting Phases in the Unconventional Compounds Strontium-Substituted Lanthanum Cuprate and Strontium Ruthenate

: We use the idea of the Wigner probability distribution (WPD) in a reduced scattering phase space (RPS) for the elastic scattering cross-section, with the help of a Tight-Binding (TB) numerical

Low-temperature nonlinear effects in the conductivity of lightly doped cuprates La2−xSrxCuO4 in antiferromagnetic state

Low-temperature conductivity of antiferromagnetic cuprates La2−xSrxCuO4 prepared by solid-phase synthesis was investigated. The concentration of strontium in the samples was 0.01, 0.005 and 0.001. In

Dressed behavior of the quasiparticles lifetime in the unitary limit of two unconventional superconductors

We compare the quasiparticle lifetime behavior in the unitary limit of two unconventional superconductors dressed by nonmagnetic impurity scattering to differentiate an anomalous functional behavior

Residual absorption at zero temperature in d-wave superconductors

In a d-wave superconductor with elastic impurity scattering, not all the available optical spectral weight goes into the condensate at zero temperature, and this leads to residual absorption. We find

Coexisting pseudo-gap and superconducting gap in the high-Tc superconductor La2-xSrxCuO4

Relationship between the superconducting gap and the pseudogap has been the subject of controversies. In order to clarify this issue, we have studied the superconducting gap and pseudogap of the

Transport Properties of D-Wave Superconductors with Impurities

We extend our earlier analysis to the electronic thermal conductivity κ and the frequency-dependent electric conductivity σ(ω) at low temperatures where quasi-particle scattering is dominated by

Pairing symmetry in cuprate superconductors

Pairing symmetry in the cuprate superconductors is an important and controversial topic. The recent development of phase-sensitive tests, combined with the refinement of several other

Magnetic excitations in pure, lightly doped, and weakly metallic La2CuO4.

We report a comprehensive neutron-scattering study of the evolution of the magnetic excitations in La[sub 2[minus][ital x]]Sr[sub [ital x]]CuO[sub 4] for 0[le][ital x][le]0.04. We first present
