This book gives a general introduction to theoretically understand thermodynamic properties and response to applied fields of mesoscopic systems that closely relate to experiments. The book clarifies many conceptual and practical problems associated with the Larmor clock and thus makes it a viable approach to study these properties. The book is written pedagogically so that a graduate or undergraduate student can follow it. This book also opens up new research areas related to the unification of classical and quantum theories and the meaning of time. It provides a scientific mechanism for time travel which is of immense fascination to science as well as society. It is known that developments in mesoscopic physics can lead to downscaling of device sizes. So, new or experienced researchers can have a quick introduction to various areas in which they might contribute in the future. This book is expected to be a valuable addition to the subject of mesoscopic physics.

Auteur
Prof. Prosenjit Singha Deo is working at the S.N Bose National Centre for Basic Sciences in Kolkata, India, since 1999. He has successfully guided several Ph.D. students leading to their Ph.D. in physics and also mentored a few postdocs. His works are mostly analytical and theoretical, but he has worked in close collaboration with experimentalists and co-authored many scientic papers with experimentalists. He has consistently worked on the problems elaborated in the book for over 25 years and more. He has also taught several courses in physics at the level of M.Sc. Before joining S. N. Bose Centre, he spent about 3 years in Europe as a postdoctoral fellow. He did his Ph.D. in physics in 1996 from the Institute of Physics, Bhubaneswar, India.
