May 9, 2014 We will try to make some sense of the Aharonov-Bohm effect, one of the Seven Pines topics. There is a great deal in the reader. The articles by Healey and Wallace are probably the ones to look at first. Michel tells me (CAG) that in the past, he has found the latter more intelligible.
I am finding it prudent to do supplementary reading; for those in the same position, I attach an excerpt from David Griffith's QM textbook. All that is really necessary is the section on the Aharonov-Bohm effect, but the earlier stuff gives a very interesting context--I had not known about the Berry's phase/geometrical phase business. Other sources are the Feynman Lectures, ch 15; and the downloads page of www.curtwittig.com. Chapter 4, perhaps supplemented by chapter 3 and the appendix, gives a very nice tutorial.
Note that both Griffiths and Wittig treat the example of a charged particle constrained to follow a circular path. If one puts that path in a region where the magnetic field is zero but the vector potential is not, the degeneracy can be lifted. Wittig gives a nice illustration showing how the energy levels are (and aren't) shifted.
The central idea is that unlike the situation in classical e&m, the magnetic vector potential in QM has observable consequences, much to everyone's surprise. Some philosophers, and perhaps some physicists, claim the effect is another example of non-locality. Others, including Feynman, say that it is a purely local effect. Clayton Gearhart
September 13, 2013 Michel Janssen will present a talk he prepared with Tony Duncan for a conference in Copenhagen this summer to mark the centenary of the Bohr atom. The title of the talk is: "Stark contrasts: the Stark effect in the old and the new quantum theory." If you want to read up on the topic ahead of time, you can do no better than read the introduction by Michael Eckert to the two papers with which Arnold Sommerfeld in effect laid the foundations for the old quantum theory. Skip the first part and read as much as you can stomach of pp. 25–60. (pdf)

To get ready for this year's symposium, Seven Pines XV on the origins of life, PIG has been commuted for a semester to a history of science graduate seminar on the topic, co-taught by historian of biology Mark Borrello. We anticipate resuming our regular PIG meetings in Fall 2011.
Please come prepared to tell us what you've been up to in the history and/or philosophy of modern physics. Suggestions as to what we're going to do this fall are also more than welcome.

October 29. Discussion leader: Clayton Gearhart. For the second session, we will read a draft paper by Massimiliano Badino of the Max Planck Institute for History of Science on Boltzmann's famous H-theorem (which is in part a response to a recent paper on the subject by Harvey Brown, Wayne Myrvold, and, again, Jos Uffink).

November 12 Discussion leader: Brian Woodcock. Collapse interpretations of
Readings: (1) Giancarlo Ghirardi's introduction to collapse theories from the Stanford Encyclopedia of Philosophy.
(2) The last chapter (Chapter 7) of David Albert's book Time and Chance (Cambridge MA: Harvard University Press, 2000), where Albert considers philosophical issues in the foundations of thermodynamics and statistical mechanics. In that chapter he first introduces quantum mechanics and the quantum measurement problem (similar to his book Quantum Mechanics and Experience). The second half of the chapter makes an interesting connection between the GRW theory of quantum state collapse and statistical mechanics. This ties our foray into collapse theories nicely together with the theme of statistical mechanics that we've had going so far. If one is already familiar with the quantum measurement problem, I recommend skipping (or skimming) ahead to p. 148 where Albert begins his discussion of the GRW collapse theory and the role it might play in the foundations of statistical mechanics.
