Introduction

Recent developments in gravity-superconductivity interactions have been summarized by several researchers. If gravitation has to be eventually reconciled with quantum mechanics, the macroscopic quantum character of superconductors might actually matter. This e-book attempts to answer one key question relating to gravity research: Is it possible to generate gravity-like fields by condensed-matter systems, in conditions accessible in a laboratory? General Relativity and lowest-order Quantum Gravity predict in this case very small emission rates, so these phenomena can only become relevant if some strong quantum effect occurs. This e-book is unique in its genre as it maintains a careful balance between different techniques and approaches in gravity and superconductivity research. It will be of interest for researchers in General Relativity and gravitation theories, in field theory, in experimental gravitation, in low-temperature and high-temperature superconductivity and in more applied fields such as telecommunications and beam propulsion technology.
