The Future is Nano


Quote by ZapperZ
Er... since when is "fermionic structures" implies chemistry and "bosonic structures" is condensed matter physics?
An online particle physics tutorial and other sources I've read have associated them this way. Fermions obey Pauli-exclusion and allow the creation of ordinary matter and bosons don't and form condensed matter.

I understand it's not a strict pairing, since some molecules have additive integer spin and exhibit some bosonic behavior. Sorry, I should have realized that that was poorly worded.

Have you looked at the section where nanoscience papers are published in Phys. Rev. Lett.?
Do you mean the "Atomic, Molecular, and Optical Physics" section? I've been looking for physical "nanoscience" articles for a while now, and I'm starting to get the impression that physicists aren't especially fond of the word.

You need to be more careful with the terminology. "Condensed matter physics" is a FIELD of study in physics. "Condensates" or "BE condensation" is a state of matter due to bosons. These two are NOT the same thing.

Ohhh, I see. Not "BE condensates," though, because that's redundant? Thank you for that post and the link to Coleman's paper.

So, do you know of any interesting links between BE condensation and nanoscience?

No, it isn't. You obviously missed the recent discovery of Fermionic condensates.

Really, I didn't know it was that obvious.

Those question marks in the last row of Colemen's broken symmetry table are pretty exciting, btw.

so what field of study is Condensates in? I always thought Plasma Physics was its own field and so since Condensates are yet a fifth state of matter (plasma being the fourth) it was natural for me to assume that Condensates are its own field by now.

BE condensates straddle both condensed matter and atomic/molecular/optics field. This is why you see such subject matter being presented at the APS March meetings.

If there's no program complimentar to condensates at my University, what do you think the chances of starting one are. There's at least two of us undergrads interested in condensates, and we've haven't started scoping out admin/faculty/staff yet, but that's a different story.

I'm more interested in what kind of national/state support I could get in Alaska. I'm under the impression that condensates are the new hot topic in physics.

Just a reminder, Pyth, that this thread is about nanoscale physics.

You might want to start a new thread in A&CG exploring specific questions of teaching certain advanced physics courses (like BECs) in undergraduate programs.
