magnetic monopole at Room Temperature - possible affect ?

New material mimics a magnetic monopole at Room Temperature presented at:
http://nextbigfuture.com/2010/04/new-ma ... opole.html

Could this affect positively the polywell somehow ?

I don't think so...

This is akin to fridge magnets that have both poles on one side and scant 'stray field' on other...

IIRC, even one true monopole would invalidate great slabs of outré hypotheses...

looks like that to me also - sort of minimal circular Halbach array - http://en.wikipedia.org/wiki/Halbach_array - but at nano scale.

smart/functional materials applications intriguing. pushing materials science for sure (temp, scale), though cant see any new fundamental physics at play yet... maybe i'm missing something...

What would it invalidate? My understanding is magnetic monopoles would simply add more terms to the equations we already have.

spot on. that is my understanding also. irrc, Maxwell breaks down/becomes inadequate, but Euler steps in to save the day as a common basis. some such.

i'm sure the Poincare conjecture, now theory, comes in there somewhere as well, but isnt critical to it. (specifically, 3 & 4 dimensional space posses specific analytic problems, hence the known amalgum of solutions we have to cover; by contrast problems in 1,2, 5 and higher dimensional spaces had for some time been solvable as a general case).

any theory, however good, is never anything more than an approximate transcript, symbolic rewriting, of 'The Laws' which actually prevail/operate, in our 'time-like' frame of reference.

whatever wurx...

ps. is there a term for them in QCD?

Magnetic monopoles would simply render Polywell and other fusion machine useless for energy generation, at least earthwise.

so long as we assume continuous monotonic trajectories (orbits) though the device centre, spherically symetric. perhaps a monopole model might be helpful in modeling asymetric/discontinuous trajectories, such as suround collisional events.

similarly, modeling a PWR by reflecting pi/2 quadrants might also give rise for a 'pseudo' term for 'monopole', albeit simply for the sake of theoretical/computational simplification. (flux reconnection analysis?)

i really dont know. it seems to me like it might have a use. what do you think?

Are you suggesting a circular magnetic Halback configuration?
Something like this?

yes, something like that.

i wasnt suggesting a 'practical' use in the Polywell; just maybe a 'theoretical/abstract' application.

but now i think, i cant really see the point.

ps. i was thinking more along these lines: http://www.lorentzcenter.nl/lc/web/2007 ... rnodub.pdf (' ... a monopole is a flux defect ...')
