Quantum Mechanics

Starting from basic principles, the book covers a wide variety of topics, ranging from Heisenberg, Schroedinger, second quantization, density matrix and path integral formulations of quantum mechanics, to applications that are (or will be) corner stones of present and future technologies.
The emphasis is on spin waves, quantum information, recent tests of quantum physics and decoherence. The book provides a large amount of information without unbalancing the flow of the main ideas by laborious detail.

The presentation in the new edition of this well-reviewed textbook is clear and goes to the core of the questions The balance between principles, concepts and applications is optimal The material presented is touching active areas of physics Supplies new views on decoherence, entanglement and path integral formulation of quantum mechanics Gives background needed to understand quantum cryptography, teleportation and computation Includes supplementary material: sn.pub/extras
