Here, the author provides a review and oversight of many views on the interpretation of quantum physics and the wide philosophical debate that still embroils this subject over 100 years since its initial development.

Written for postgraduate students as a pedagogical introduction to string theory. Extending beyond an introductory review of the subject, it encompasses key analytical and numerical tools, as well as useful physical models in applications. The book is augmented with numerous codes in addition to problems and exercises.

A Modern Course in Quantum Field Theory provides a self-contained pedagogical and constructive presentation of quantum field theory. Written for advanced students the work provides complete material for a two or three semester course, ad includes numerous problem exercises, some with detailed solutions

Whilst general relativity is not complex in its formulation, the physical interpretation of its mathematical descriptions gives rise to a range of exciting consequences in cosmology. A detailed understanding of general relativity is therefore a prerequisite for students wishing to pursue further courses or commence research projects in cosmology and its various captivating subfields including black holes and gravitational waves.This is not a book on general relativity per se and the author’s treatment of this fundamental topic is concise, with the required differential geometry summarized in an appendix. Instead, the primary goal of this book is to allow students to understand in a critical way two pillars of modern theoretical physics: inflationary theory, and quantum black holes and the information-loss problem. Accordingly, the book extensively introduces black holes and cosmology before proceeding to the important issues found in inflation and the information-loss problem. Other important topics discussed in detail include the cosmological constant and its relation to dark energy and an introduction to quantum field theory on curved backgrounds.Including numerous exercise problems, the material provides a single rigorous text for advanced students in theoretical physics and mathematics requiring an introduction to the implications and interpretation of general relativity in areas of cosmology. Readers of this text will be well prepared to follow the theoretical developments in the field and undertake research projects as part of an MSc or PhD programme.
