Abstract

The formula frequently used to describe the c-axis infrared response of the coupled electron-phonon system of bilayer cuprate superconductors and providing important insights into the physics of these materials has been originally obtained at the level of the phenomenological multilayer model. Here we derive it using diagrammatic perturbation theory.

Abstract (in Czech)

Formule často používaná pro popis infračervené odezvy elektron-fononového systému dvouvrstvých kuprátových supravodičů, která poskytuje důležitý vhled do fyziky těchto materiálů, byla původně získána z fenomenologického modelu. V článku je odvozena pomocí diagramové poruchové teorie.
