A brief review of the developments of statistical physics, especially during the latter half of this century, is given, with focus on many body theory, followed by discussions of the future outlook or directions in several selected areas.
Since the turn of the century, the increasing availability of photoelectron imaging experiments, along with the increasing sophistication of experimental techniques, and the availability of computational resources for analysis and numerics, has allowed for significant developments in such photoelectron metrology. Quantum Metrology with Photoelectrons, Volume 2: Applications and advances discusses the fundamental concepts along with recent and emerging applications. Volume 2 explores the applications and development of quantum metrology schemes based on photoelectron measurements. The author begins with a brief historical background on 'complete' photoionization experiments, followed by the details of state reconstruction methodologies from experimental measurements. Three specific applications of quantum metrology schemes are discussed in detail. In addition, the book provides advances, future directions, and an outlook including (ongoing) work to generalise these schemes and extend them to dynamical many-body systems. Volume 2 will be of interest to readers wishing to see the (sometimes messy) details of state reconstruction from photoelectron measurements as well as explore the future prospects for this class of metrology.

With the emergence of Quantum mechanics arrived the prospect of further development in technology. New areas of research and development came into the picture, one of them being Quantum communication. In 1991, the first protocol of Quantum cryptography and quantum non-duality attracted physicists, mathematicians, and computer scientists to explore the mysterious ways of the quantum world. Since then, quantum communication has evolved to an astonishing extent. Ultra-high-speed internet, computational power, optimization, and security have paved the way for innumerable possibilities ahead. This survey intends to investigate the concepts and applications of quantum communication. In this review article, we try to give an idea of quantum communication background by shedding light on polarization and entanglement, following which, we give a brief survey of its applications such as quantum teleportation, quantum key distribution, secure direct communication, and quantum memories. The study concludes with a discussion on the future outlook of this emerging paradigm.
