Here is a readable and intuitive quantum mechanics text that covers scattering theory, relativistic quantum mechanics, and field theory. This expanded and updated Second Edition - with five new chapters - emphasizes the concrete and calculable over the abstract and pure, and helps turn students into researchers without diminishing their sense of wonder at physics and nature. As a one-year graduate-level course, Quantum Mechanics II: A Second Course in Quantum Theory leads from quantum basics to basic field theory, and lays the foundation for research-oriented specialty courses. Used selectively, the material can be tailored to create a one-semester course in advanced topics. In either case, it addresses a broad audience of students in the physical sciences, as well as independent readers - whether advanced undergraduates or practicing scientists.The two solutions 1N1a#39;) are independent and clearly have opposite signs for the rest energy, E0 = im (the eigenvalue of i6/0t). ... e+i[pa#39;x_EPt] : ea#39;fiipumaquot; , Ac(-)(x, t) = (aPX-W1 = e+*a#39;Pa=~, (13.33) We recognize the expression in brackets as the scalar ...
