5 Quantum Theory of Radiation
... The interaction Ĥ2 couples to the intrinsic magnetic moment of the particles only. The intrinsic magnetic moment is the moment associated with spin angular momentum. Hence, the matrix element you calculated in (a) does not involve the total magnetic moment of the particles. The orbital component ha ...

14 The Postulates of Quantum mechanics
... • Postulate 2: To every physically observable there exist a linear Hermitian operator. • Postulate 3: In any measurement of the observable associated with operator Â, the only values that will ever be observed are the eigenvalues ai , which satisfy the eigenvalue equation Âgi = ai gi . • Postulate ...

Is Quantum Mechanics Incompatible with Newton`s First Law of
... Newton’s first law is a special case of his second law since the absence of a force leaves the body in its original state of uniform motion. We shall see that Newton’s second law can be derived from Schrödinger’s equation, which was set up to yield Newton’s laws of motion in the classical limit. So ...

Alternatively, if the initial conditions are changed not by displacing the initial point, but by changing the angle of the shot, we see that the new trajectory diverges from the original one at a linear rate. The conclusion we draw is thus that the divergence of what we call “near ...
