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).

Statistical Physics - DAMTP

Statistical mechanics is the art of turning the microscopic laws of physics into a de-scription of Nature on a macroscopic scale. Suppose you’ve got theoretical physics cracked. Suppose you know all the funda-mental laws of Nature, the properties of the elementary particles and the forces at play between them.

Black Body Radiation - Physics

Before Planck it was assumed that these could have any value of energy but Planck decided that the energy must go up in discrete amounts (quantised) because the frequencies of the oscillating electrons could only take certain values.

Classical Dynamics - DAMTP

The fundamental principles of classical mechanics were laid down by Galileo and New-ton in the 16 thand 17 centuries. In 1686, Newton wrote the Principia where he gave us three laws of motion, one law of gravity and pretended he didn’t know cal-culus. Probably the single greatest scienti c achievement in history, you might think
