New tools of presentation and mathematical treatment emerged and the subject matter of quantum mechanics has gone through significant changes, over the past decades. A text book 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 and as solved examples. Fundamental discoveries that are the foundation of modern quantum mechanics, solution of Schr dinger's wave equation for 1D problems and their importance, matrix and vector formulation of quantum mechanics, transformations, symmetries and conservation laws, angular and spin momenta, solution and application of Schr dinger equation to central potentials, time-independent perturbation theory, variational method, WKB approximation, quantum theory of scattering, many-particle systems and their quantum mechanical treatments, time-dependent perturbations and the interaction of fields with matter, relativistic quantum mechanics, quantization of fields and the second quantization are covered in the book. The contents of book are divided into 12 chapters. Some of the special features of book are: It provides everything a student needs to know for succeeding at all levels of the under graduation and graduation studies. It covers most of the topics that are taught udder (a) elementary, (b) intermediate, and (c) advance courses of quantum mechanics, across the various universities/colleges. It has detailed and elegant mathematical treatment with contemporary style of interpretation and presentation in simple English. Solved examples and unsolved exercises are made 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. It will serve as a valuable textbook to the students who enrol for Bachelor of Science, Master of Science, and Doctor of Philosophy (Ph.D.) degrees in the subjects of Physics, Chemistry and material science across the various Universities/Institutions in India, south Asian countries, USA and Europe.
