An earlier edit (Angela) of the page introduced the Berry phase with something that is also found on Eric Weisstein's World of Science - but that description is misleading, so I replaced it. I did try to put the reference to "rotation of a particle" in further below, because I liked it as an example of what one actually could do in an experiment. But general rotations alone don't create Berry phases, even when they're slow.
- As I said on your talk page, I'm not an expert! I'm glad you checked it. I was just aiming to get some sort of basic introduction to the page and that was the information I happened to come across first. Angela 04:20, Sep 21, 2003 (UTC)
I believe when you mention the AB effect as a manifestation of geometric phase you mistankingly assign the adiabatic parameter to be the magnetic field inside the solenoid -- which is taken to be constant and thus is not adiabatically varied. The true adiabatic parameters are the ones describing the rotation of the quantum mechanical system around the solenoid. Johnny 16:23, Apr 20, 2006 (UTC)
The link to the paper on Fine Structure Constant is not to be credited in my opinion.
Agreed. I removed the link and replaced it by a resource letter by an expert group (Anandan et al.)
[edit] Examples
I felt the article needed some simple examples to help the reader understand what it is about. I added two. --ShanRen 22:28, 25 February 2007 (UTC)
