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.

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).

The Schrödinger Equation in One Dimension

In fact, the general form of the Schrodinger Equation is known as the Time-Dependent Schrodinger Equation (TDSE): − 2 2m ∂2Ψ(x,t) ∂x2 +U(x,t)Ψ(x,t)=i x,t) ∂t. (7.9) When the potential energy is independent of time (true for many interesting systems), wave functions satisfying the TDSE can always be written as (in 1 D)
