Lectures on Quantum Mechanics

"Lectures on Quantum Mechanics" is a comprehensive textbook that provides a conceptually grounded introduction to quantum mechanics while also offering a fascinating overview of modern theoretical physics. The new edition is engagingly written and richly illustrated, making it easier to understand complex topics. The book begins with a brief overview of various physical subjects, including nanotechnology, statistical physics, materials science, astrophysics, and cosmology. The main part of the book addresses both established and emerging aspects of quantum mechanics, including the Schrödinger equation, Hilbert space, the algebra of observables, the hydrogen atom, spin, and the Pauli principle. Additionally, modern concepts such as entangled states, Bell's inequality, quantum cryptography, and quantum teleportation are discussed. The new edition includes numerous problems with detailed solutions as well as an introduction to the mathematical tools necessary for understanding quantum mechanics.
