The book provides state-of-the-art information describing the Quantum Field Theory. Quantum Field Theory is now identified as an effective tool not only in Particle Physics but also in Nuclear Physics, Condensed Matter Physics, Solid State Physics and even in Mathematics. This book is a compilation of some present applications of Quantum Field Theory to these mentioned fields of modern physics and mathematics, in order to give a more profound understanding of known facts and unsolved problems.

This book provides insight into major facets of the physics of quantum gravity. The application of quantum field theory for explaining gravity is one of the main problems in contemporary elementary Physics. It has been in existence for nearly a century, but a definite answer is yet to be determined. Loop quantum gravity and string theory have answered several answers associated with this problem, but they have brought with themselves a huge set of added questions. Apart from these two theories, several other alternative theories have also been developed over the decades. Renowned authors from...

This book presents an updated account of the research and development undergoing in the domain of quantum theory. Quantum theory is the primary theoretical approach that aids one to favorably understand the atomic and sub-atomic worlds which are too far from the cognition on the basis of general intuitions or experiences of daily-life. It is a very rational theory in which a balanced system of hypotheses and relevant mathematical methods facilitate exact explanation of the dynamics of quantum systems whose measurements are systematically influenced by objective uncertainties. Quantum theory...
