Superconducting Shielding: Design and Properties

This lecture covers the basic properties of superconductors, focusing on magnetic shielding and the Meissner effect. It explains how superconductors expel magnetic fields, creating field-free spaces using materials like lead. The lecture also delves into the macroscopic wave function of superconductors and the concept of superfluid velocity. Additionally, it discusses the properties of the macroscopic wave function, including the probability density of Cooper pairs and the supercurrent density. The instructor emphasizes the importance of designing superconducting shields to prevent the transmission of perpendicular magnetic fields and the need to homogenize magnetic fields. The lecture concludes with a discussion on single-spin detection for biological research and the ongoing quest for single-spin imaging.
