A QUALITATIVE OVERVIEW OF THE MECHANISMS OF SUPERCONDUCTIVITY
Author: SHAILAJ KUMAR SHRIVASTAVA
Category: Engineering, Science and Mathematics
Abstract:
The mechanism of superconductivity continues to be one of the most fascinating and challenging topics in condense matter physics. The discovery of high-Tc cuprate superconductors and iron based superconductors has challenged the classical theories of condensed matter physics and opened a new chapter of strongly correlated electron systems. The key question of superconductivity is the nature of mechanism of pairing of carriers. The electron phonon interaction or spin fluctuations are considered to be central to the mechanism of superconductivity. In this article attempt has been made to highlights the brief outcome of various models and theories on the mechanism of superconductivity.
Keywords: High-Tc superconductors, electron- phonon interaction, spin fluctuation, pairing mechanism
