QUANTUM GRAVITATIONAL IMPRINTS ON COSMOLOGY

Quantum Gravitational Imprints on Cosmology surveys the remarkable advancements in our understanding of the interface between quantum gravity theories and cosmology that have been achieved over the past four decades. The current cosmological model relies on inflationary theories, which incorporate baryosynthesis, dark matter, and dark energy. Supported by precise cosmological data, it necessitates physics beyond the standard models of fundamental forces, including gravity. This connection between macroscopic gravity on large scales and quantum gravity on the smallest scales is where quantum gravity's nature becomes evident. Quantum gravity effects alter our classical understanding of gravitational phenomena as described by general relativity, leading to observable deviations from the conventional cosmological model. The field of cosmoparticle physics explores the interplay between the micro and macro worlds, offering insights into the development of quantum gravity and its cosmological implications.

These fascinating developments are explained at a level accessible to advanced PhD students, making the book a valuable resource for early-career researchers approaching these fields for the first time or interested in exploring them in greater depth.

Readership: The target readership is a wide academic audience, professional or interested in modern cosmology, astrophysics and particle physics and their fundamental relationship. It can be used as a text book for courses in theoretical physics, cosmology, high energy physics and astrophysics, astroparticle physics at the undergraduate, graduate and postgraduate levels. The book may be useful for specialists in various particular fields of astronomy and particle physics to find possible application of their experience in the studies at the frontiers of fundamental knowledge. In particular, it would be very beneficial for Master's or PhD students in cosmology and particle physics, and also for postdocs and even for professors and other senior researchers in this field. Even though our book is primarily a monograph, it can be used for advanced PhD courses on cosmology and particle physics as well. The current ideas on the Dark Universe, Black holes, as well as on the fundamental structure of micro- and macro worlds are of interest for the general audience and the presentation of these ideas, avoiding technical details, but giving their qualitative intuitive understanding can attract a much wider audience. The book can also be of interest to applied mathematicians, who are working on various aspects of quantum gravity. The field of quantum gravity has surprisingly used various avenues of mathematics which are not much talked about in contemporary theoretical physics and this has led to an increased attention of mathematicians in this field, and this book can allow mathematicians, right from advanced PhD students to Professors, to perhaps identify new areas where novel mathematics could be applied in physical systems.
