Quantum Mechanics in High-Temperature Superconductors

Abstract

High-temperature superconductivity remains one of the most intriguing and unresolved challenges in condensed matter physics. While traditional superconductors are well understood through BCS theory, high-temperature superconductors (HTS) defy this explanation and require a deeper quantum mechanical framework. This paper explores the quantum mechanical phenomena that underlie high-temperature superconductivity, emphasizing the role of electron-electron interactions, quantum coherence, and the pairing mechanisms. We also examine recent advances in understanding the relationship between quantum fluctuations, spin dynamics, and the material’s ability to conduct electricity without resistance at elevated temperatures.
