Lecture Notes on Special Relativity - Macquarie University

Chapter 1 Introduction: What is Relativity? U the end of the 19th century it was believed that Newton’s three Laws of Motion and the associated ideas about the properties of space and time provided a basis on which the motion of matter could be completely understood.

Particle Spin and the Stern-Gerlach Experiment

Chapter 6 Particle Spin and the Stern-Gerlach Experiment The spin of an elementary particle would appear, on the surface, to be little different from the spin of a macroscopic object – the image of a microscopic sphere spinning around some axis

Observables and Measurements in Quantum Mechanics

haustive collection of results obtained when measuring some physical property, or observable, of the system. This linking of particular states with particular measured results provides a way that the observable properties of a quantum system can be described in quantum mechanics, that is in terms of Hermitean operators.

Some Useful Properties of Complex Numbers

Real and imaginary parts The real and imaginary parts of the complex number z= x+ iyare given by Real part Rez= x Imaginary part Imz= y: (1) with Re(az 1 +bz 2) = aRe(z 1)+bRe(z 2) and Im(az 1 +bz 2) = aIm(z 1)+bIm(z 2) (2) where aand bare both real numbers.

The Wave Function - Macquarie University

The wave function or wave packet so constructed is found to have essentially zero ampli- tude everywhere except for a single localized region in space, over a region of width 2∆ x , i.e. the wave function Ψ( x , t ) in this case takes the form of a single wave packet, see Fig. (3.3).

Probability, Expectation Value and Uncertainty

The uncertainty of the observable A is a measure of the spread of results around the mean #Aˆ!. It It is defined in the usual way, that is the difference between each …

The Schrödinger Equation in Three Dimensions

In separating the θ-dependent part of the TISE, the separation constant was taken to be l(l+1). It turns out that the solutions to the θ-equation, i.e., the Θ(θ), are of two kinds. One kind remains finite for all 0 ≤ θ ≤ π for non-negative integer values of l and the other kind blows up at θ = 0
