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).

Quantum Mechanics Made Simple: Lecture Notes

Quantum mechanics has played an important role in photonics, quantum electronics, and micro-electronics. But many more emerging technologies require the understanding of quantum mechanics; and hence, it is important that scientists and engineers understand quantum mechanics better. One area is nano-technologies due to the recent advent of nano-

Lecture Notes in Quantum Mechanics - BGU

The lecture notes are self contained, and give the road map to quantum mechanics. However, they do not intend to come instead of the standard textbooks. In particular I recommend: [1] L.E.Ballentine, Quantum Mechanics (library code: QC 174.12.B35). [2] J.J. Sakurai, Modern Quantum mechanics (library code: QC 174.12.S25). [3] Feynman Lectures ...

THE MATHEMATICS OF QUANTUM MECHANICS

In addition to the mathematics of quantum mechanics, we’ll spend another five hours exploring the “physics” of quantum mechanics. We’ll first explain the behaviour of quantum particles without quantifying it. We’ll then consolidate the two so you have a good understanding of how we use mathematics to model the physical quantum world.
