Un tiempo de vida de dispersión autoconsistente constante en el superconductor rutenato de estroncio



Palabras clave:

Tiempo de vida de superconductor constante, Rutenato de estroncio, Superconductividad no convencional, Atenuación de ultrasonidos, Conductividad térmica electrónica, Método autoconsistente


En este trabajo numérico, encontramos un tiempo de vida superconductor de dispersión autoconsistente constante para dos valores diferentes de los parámetros, a saber, la fuerza atómica inversa y el desorden estequiométrico en el superconductor no convencional triplete rutenato de estroncio. Este hallazgo es relevante para los experimentadores, dado que las expresiones para la atenuación de ultrasonido y la conductividad térmica electrónica dependen del tiempo de vida de dispersión superconductora, y un tiempo de vida constante se ajusta a los datos experimentales fuera del equilibrio térmico. Este descubrimiento ayuda a los experimentalistas en su interpretación de los datos adquiridos. Además, encontramos partes imaginarias diminutas de la energía propia que se asemejan a la brecha delgada del modelo de Miyake-Narikiyo, pero fuera del límite de dispersión elástica unitaria, y por debajo del valor umbral de brecha cero de 1,0 meV.
