Some Unusual Topics in Quantum Mechanics

Pankaj Sharan is a professor retired from the Department of Physics at Jamia Millia Islamia, New Delhi. His research interests are chiefly in quantum mechanics, quantum field theory and general relativity. Over a teaching career spanning four decades, he has taught courses on quantum mechanics, quantum field theory, classical mechanics, general relativity and mathematical physics. He is the author of the book Spacetime, Geometry and Gravitation.

Position operators of non-relativistic quantum mechanics.- A bundle picture of quantum mechanics.- A beam of particles = a plane wave?.- Star-product formulation of quantum mechanics.- Can there be a non-linear quantum mechanics?.- Interaction = exchange of quanta.- Proof of Wigner's theorem.

"The author takes care to introduce the new concepts in a gradual manner to make it accessible to a reader accustomed only with the standard perspective. This makes the book very suitable for self-study. ... A good list of references is provided for further exploration of each topic. This is a book which will greatly benefit a serious curious student of the subject. It deserves to be in any good library and also in the bookshelves of experts." (Amitava Raychaudhuri, zbMATH 1483.81002, 2022)
