Nonequilibrium Statistical Mechanics I - Chris Jarzynski

[@jiangxu3895]

Wow， I think I might not be able to finish this lecture, since I enjoy watching youtube short video SO MUCH. Before I watch this video, I have a question, since W>= delta-F, why in Crook-Theoreom there are some cases where W can be less than delta-F. I watched this video to 40:48, and Chis's explanation delighted me. My answer to this question is that, in microscopic world, for different particles, some particle may happened to be knocked by another molecule at the same direction as the work corrdinate lamda, in this case, the observed work could be less than the delta F. But in essence, the total work (not observed work but also taking account of the one by the other molecule), is still more than the delta-F. Amazing lecture!!!

Pretty insightful, thanks for sharing. Are the lecture notes available anywhere?

Ooh, this is actually the guy behind this famous nonequilibrium inequality: en.wikipedia.org/wiki/Jarzynski_equality . That explains why he understands stuff so well! Plus he also explains it well! Thanks for sharing

I really love Chris's teaching!!! This video gives me so much memory

@Bhat Saqib no it isnt. Nonequilibrium statistical mechanics typically goes at the graduate level

Does "system out of equilibrium" imply gain/loss of energy during the process?

spectacular Lecture!! I have a question, is there some good reference (books) ?

Got a short Q, maybe you can help me. He described the volume around the certain points in phase space. Can anyone explain the meaning of this volume to me ? (The little box around x0 and xTau). He said how those volumes behave with respect to the jacobian, but as I’m not having a lot of experience in this field I don’t really see the interpretation of this volume. What is its meaning?
