Chapter 1: Introduction to Superconductivity
High-temperature superconductors represent a groundbreaking shift in condensed matter physics. Recent findings related to bilayer nickelates, particularly La3Ni2O7, have brought us closer to realizing lossless electrical transmission—an ideal goal for modern technology. Unlike conventional superconductors that operate at frigid temperatures, high-Tc (critical temperature) superconductors function at more manageable temperatures, making this dream increasingly achievable. The discovery of superconductivity in La3Ni2O7 under pressure not only enhances our understanding of this phenomenon but also opens doors to innovative and efficient technologies. Picture a future where energy loss in power distribution is significantly diminished, leading to advancements in quantum computing.
The Dance of Electrons
The superconductivity of La3Ni2O7 is driven by the complex interplay between electrons and the material's lattice structure, known as electron-phonon coupling (EPC). While this interaction is essential for superconductivity, it is not solely responsible for the high-Tc observed in La3Ni2O7. Instead, it is the sophisticated balance between EPC and electron-electron interactions that amplifies superconductivity. This intricate relationship underscores the complexity of quantum materials, emphasizing the necessity for a comprehensive understanding of their properties to fully utilize their capabilities.
Section 1.1: The Role of Pressure in Superconductivity
The application of pressure during experiments with La3Ni2O7 acts as a crucial factor in achieving its superconducting state. Under increased pressure, La3Ni2O7 undergoes structural transformations that enhance electron-phonon interactions, which, in tandem with electron-electron interactions, lead to high-Tc superconductivity. This ability to modify material characteristics through pressure allows for the exploration of new states of matter and the discovery of materials with extraordinary properties. The potential for finding materials that can operate as superconductors at room temperature could revolutionize energy transmission and technological advancements.
