Preface

To unravel the nature of the emergent phenomena in strongly correlated many-body systems is one of the central challenges in theoretical and experimental research. Unexpected and exotic properties of these systems open active areas of study in the field of condensed matter physics. One of the remarkable phenomenon of these correlated systems was the discovery of superconductivity by Onnes in 1911. Since then, a lot of experimental and theoretical research has been done to describe this phenomenon. The discovery of modern superconductors, such as high-Tc, organic, two band, and some others, presented another criticism for the theoretical physicist. The possible superconductivity mechanism of these systems remains one

Most researchers believe that their superconductivity mechanism could not be explained within the BCS theory. At present, there is no mechanism to describe all the properties of these superconductors. Many different models such as the exciton model, plasmon model, bipolaron model, magnon model, spin fluctuation model etc., have been proposed. All of these models are evaluated by presenting new

In this regard, this book includes valuable theoretical and experimental discussions about the properties of superconductors. Here you will find valuable research

The main topics of the book are organized in five chapters, as described below.

Chapter 1 contains a brief discussion about the progress in superconductivity.

Chapter 3 deals with the electromagnetic properties of bulk high-temperature superconductors (HTS), which can be used in magnetic systems for various

Chapter 2 discusses the experimental techniques to measure microwave absorption.

Chapter 4 focuses on the generalized BCS equations to discuss high Tc superconductors.
