Hole Superconductivity

Johan, What do you think of the following, which echos some of your ideas... Hole Superconductivity Superconductivity occurs due to pairing of hole carriers, and is driven by the fact that paired holes can propagate more easily (have a smaller effective mass) than single holes. As a consequence, the...

I bumped into a good overview of superconductor terminology on Joe Eck's site. http://www.superconductors.org/terms.htm Some things I found particularly interesting...

Furthermore there are other materials than diamond which present possibilities. Suffice to say that not one of the ceramic materials being studied at present has the required characteristics. Maybe one will be discovered in future but the present materials are all restricted to be at, and below abo...

What do they mean "make electrons behave as if they were in magnetic fields" ? My naive view would be that its not producing a bulk magnetic field, that is required by the Polywell requires, not even if layers are stacked.

Thanks Johan, I appreciate your response. It restores confidence in considering your views. It is human nature to get caught up defending our positions and we all get caught out from time to time. In your case however, given the battle you've picked against the core beliefs of some strong incumbents...

Johan, In another post you ask for an example of inflamatory language, then you provide one straight away. Who said they were any good? The University of Chicago is different. At least according to the recent graduate I spoke to. I doubt it very much. I have not yet seen any worthwhile physics comin...

I favour the view that if EMC2 jump-start the competition, the competition may end up patenting some critical part of the process, and then be able to form a cartel themselves. In either case that: ⋅  EMC2 are going to form a cartel, or ⋅  EMC2 don't want anyone else forming a ca...

I didn't know what ECR & ICR were, so wikipedia helped out. ECR = Electron cyclotron resonance Electron cyclotron resonance is a phenomenon observed both in plasma physics and condensed matter physics. An electron in a static and uniform magnetic field will move in a circle due to the Lorentz fo...

Edit: Click here to check out your own random xkcd cartoon. xkcd.org is one of my favourite web spots (a webcomic of romance, sarcasm, math, and language.) I notice some others here are tuned in on it too. What are your favourites? Perhaps I'm overtired, but this new one had me chuckling for a few o...
