Introductory Quantum Mechanics

Viac o knihe

This best-selling quantum mechanics text's third edition offers detailed explanations for students and a comprehensive subject list for professors, reflecting the ongoing evolution of physics. A new chapter focuses on relativistic waves, starting with basic concepts and leading to the derivation of the Klein-Gordon equation. It explores Dirac theory, the four-dimensional spin operator, and introduces covariant relativistic quantum mechanics. The revision includes updated discussions on quantum-well configurations related to quantum dots and wires, essential for semiconductor technology. Utilizing symmetry principles, the transfer matrix method is developed to recover the Kronig-Penny dispersion relation. The section on impurity semiconductors has been revised, adding a new subsection on the p-n junction. A fresh description of the Hartree-Fock model is included, providing a method for approximating atomic wavefunctions and eigenenergies, complementing the previously introduced Thomas-Fermi model. Additionally, the edition features new intriguing problems, many with solutions, and an informative periodic chart on the inside flap of the front cover. As in previous editions, the text begins with a review of classical mechanics and progresses through two parts that develop quantum theory.
