Josephson Plasma Resonance in High Temperature Superconductors: A Test of Interlayer Tunneling Theory

TL;DR

This paper calculates the Josephson plasma frequency using interlayer tunneling theory and confirms its consistency with experimental data in high-temperature superconductors, supporting the theory's validity.

Contribution

It provides a theoretical computation of Josephson plasma frequency that aligns with experimental observations in specific high-temperature superconductors.

Findings

Theoretical estimates match experimental measurements.

Supports the interlayer tunneling theory for high-temperature superconductors.

Validates the use of Josephson plasma resonance as a test for superconducting theories.

Abstract

Josephson plasma frequency is computed within the interlayer tunneling theory and compared against the experimental results in Tl_2Ba_2CuO_y and La_{2-x}Sr_xCuO_4. It is shown that the theoretical estimates are fully consistent with the recent experiments.
