Relativistic Quantum Mechanics: An Easy Introduction

This book has been written in such a manner that anyone familiar with the basics of relativity and quantum mechanics should be able to work through it without much difficulty. The book has been written in a clear and lucid manner with an eye on a wide angle of students who are encouraged to study the book on their own. It includes a brief chapter on relativity in which the notation employed in relativistic quantum mechanics is explained with particular attention to covariant and contravariant vectors and derivatives and related topics. The Klein-Gordon equations for a free particle as well as for charged particles in electromagnetic field are derived along with their non-relativistic limits. The Dirac equation is discussed in detail. One chapter is devoted to the basics of scattering calculations in relativistic quantum mechanics and gives the first steps towards QED. Seven useful appendices and a number of problems are also included in the book. This book will be useful for final year undergraduate and graduate students of US universities, and for M. Sc. And M. Phil students of universities in the subcontinent.
