Self-Consistent Study of the Superconducting Gap in the Strontium-doped Lanthanum Cuprate
Pedro Contreras, Dianela Osorio, Anjna Devi
This work is aimed at numerically investigating the behavior of the Fermi energy in Strontium-doped Lanthanum Cuprate, using a numerical zero temperature elastic scattering cross-s…
The collision frequency in two unconventional superconductors
Pedro Contreras
The collision frequency (also known as the inverse scattering lifetime) can be self-consistently calculated from the imaginary part of the zero-temperature elastic scattering cross…
Tight-Binding Superconducting Phases in the Unconventional Compounds Strontium-Substituted Lanthanum Cuprate and Strontium Ruthenate
Pedro Contreras, Dianela Osorio, Eugeniy Yurievich Beliayev
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 (T…
The two-dimensional density of states in normal and superconducting compounds
P. Contreras, A. Devi, D. Uzcategui +1
The present work represents a review for the numerical calculation of the density of states (DoS) for two-dimensional tight-binding models with first neighbors in its normal state…
Non-magnetic tight binding disorder effects in the sheet of
P. Contreras, Dianela Osorio, S. Ramazanov
Inspired by the physics of the Miyake - Narikiyo model (MN) for superconductivity in the γ sheet of to investigate numerically the behavior caused by a non-magnetic dis…
Dressed behavior of the quasiparticles lifetime in the unitary limit of two unconventional superconductors
P. Contreras, Dianela Osorio, E. Yu. Beliayev
We compare the quasiparticle lifetime behavior in the unitary limit of two unconventional superconductors dressed by non-magnetic impurity scattering to differentiate an anomalous…
