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... BCS Theory : The first widely-accepted theory to explain superconductivity put forth in 1957 by John Bardeen, Leon Cooper, and John ...

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...

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 cartel there is nothing obse...

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 force....

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...

Funnily enough, I bumped into the GS2: Gyrokinetic Microturbulence Project only yesterday, though I can't judge how suitable it is. Fast microstability assessment Linear microstability growth rates are calculated on a wavenumber-by-wavenumber basis with an implicit initial-value algorithm in the bal...
