This advanced monograph, 'Quantum Mechanics, Selected Topics,' by Zeldovich and Perelomov, serves as a crucial bridge between standard quantum mechanics textbooks and specialized research literature. It delves into complex non-relativistic quantum mechanics, offering detailed treatments of scattering theory, multidimensional quasi-classical approximation, non-stationary problems for oscillators, and the theory of unstable particles. Tailored for postgraduate students and researchers, the book provides rigorous theoretical insights and advanced methodologies often overlooked in introductory texts. Its primary aim is to uncover sophisticated and interesting information hidden within the depths of quantum mechanics, making it an indispensable resource for those seeking a deeper understanding of the subject.
Key themes
- Scattering Theory and Interactions
- This theme explores how quantum particles interact and scatter off each other or potential fields. It delves into the mathematical formalism for calculating scattering amplitudes, cross-sections, and the implications for understanding fundamental forces and particle structure. The book provides a detailed treatment of various scattering formalisms, including the Lippmann-Schwinger equation and phase shifts.
- Time Evolution and Unstable Systems
- This theme explores the dynamics of quantum systems, particularly focusing on non-stationary problems for oscillators and the fascinating theory of unstable particles. It delves into how quantum states evolve in time and the mechanisms of decay for particles with finite lifetimes, challenging classical notions of stability.
- Approximation Methods in Quantum Mechanics
- The book emphasizes the necessity and power of approximation techniques, particularly the multidimensional quasi-classical (WKB) approximation, for solving problems where exact analytical solutions are intractable. This theme highlights the balance between mathematical rigor and practical solvability in quantum mechanics.
