A Textbook on Modern Quantum Mechanics de A C Sharma

A Textbook on Modern Quantum Mechanics

Autor A C Sharma
en Limba Engleză Paperback – 4 oct 2024
Over the course of the past two to three decades, new tools of presentation and mathematical treatment have emerged and the subject matter of quantum mechanics has gone through significant changes. A Textbook on Modern Quantum Mechanics presents the selected elementary, intermediate, and advance topics with rejuvenated approach to the subject matter. Newly merged topics from contemporary physics and chemistry are included in the text as well as solved examples. The book covers: (i) fundamental discoveries that are the foundation of modern quantum mechanics; (ii) solution of Schrödinger’s wave equation for 1D problems and their importance; (iii) matrix and vector formulation of quantum mechanics; (iv) transformations, symmetries, and conservation laws; (v) angular and spin momenta; (vi) solution of Schrödinger equation for central potentials; (vii) time-independent perturbation theory, variational method and WKB approximation; (viii) quantum theory of scattering; (xi) many-particle systems and their quantum mechanical treatments; (x) time-dependent perturbations and the interaction of fields with matter; (xi) relativistic quantum mechanics; and (xii) quantization of fields and the second quantization.
Key Features:
    • It provides everything a student needs to know for succeeding at all levels of the undergraduate and graduate studies.
    • It covers most of the topics that are taught under (a) elementary, (b) intermediate, and (c) advance courses of quantum mechanics at universities and colleges.
    • It has detailed and elegant mathematical treatment with contemporary style of interpretation and presentation in simple English.
    • Solved examples and unsolved exercises that are part of each chapter to consolidate the readers' understanding of fundamental concepts.
    • The subject matter of the book is well tested on the students taught by the author over a period of 30 years.
This is a valuable textbook for students pursuing Bachelor of Science, Master of Science, and Doctor of Philosophy (PhD) degrees in the subjects of Physics, Chemistry, and materials science in India, South Asian countries, the United States, and Europe.
