An advanced quantum mechanics textbook that provides a unique pedagogical introduction to high-level topics in the field.
Marcos Mariño is Professor in Mathematical Physics at the University of Geneva. He has held postdoctoral positions at Yale, Rutgers and Harvard, and he was a junior staff researcher at the CERN Theory Division. His research focuses on mathematical aspects of quantum field theory and string theory. He has previously authored the book Instantons and Large N: An Introduction to Non-Perturbative Methods in Quantum Field Theory (Cambridge, 2015).
'This volume dwells on three advanced and useful approaches to nonrelativistic quantum theory: the WKB method in exact form, phase-space quantization (Weyl--Wigner, Husimi), and path integrals. A majority of the covered topics are ignored by mainstream textbooks, making this text quite innovative. The exposition is comprehensive and pedagogically oriented, with numerous concrete examples detailed. This will prove a valuable textbook for academics and students aiming beyond basic quantum theory, to make them fluent and assist their teaching in several areas that actively serve in current research.'
