Study of quantum phase changes reveals surprising relationship between magnetism and electricity
U.S., German and Austrian physicists studying the perplexing class of materials that includes high-temperature superconductors are reporting this week the unexpected discovery of a simple "scaling" behavior in the electronic excitations measured in a related material. The experiments, which were conducted on magnetic heavy-fermion metals, offer direct evidence of the large-scale electronic consequences of "quantum critical" effects.
The experimental and theoretical results are reported this week in the Proceedings of the National Academy of Science by physicists at Rice University in Houston; the Max Planck Institute for Chemical Physics of Solids and the Max Planck Institute for the Physics of Complex Systems, both in Dresden, Germany; and the Vienna University of Technology in Austria.
"High-temperature superconductivity has been referred to as the biggest unsolved puzzle in modern physics, and these results provide further support to the idea that correlated electron effects -- including high-temperature superconductivity -- arise out of quantum critical points," said Rice physicist Qimiao Si, the group's lead theorist.

Open borders ping.
Foodie ping list ping.

Could that be why they call it electromagnetism?
Quantum fractals? High Temperature Superconductivity? Tell the truth Decimon, you didn’t have a lot of dates in high school did ya? (Just joking, my social calendar in high school was nothing to write home about)
I fractaled my arm when I was a kid, and it was a quantum break.
Then you think I understand this stuff? Ha ha ha ha ha ;-)
“A quantum fractal is a wavefunction with a real and an imaginary part continuous everywhere, but differentiable nowhere. This lack of differentiability has been used as an argument to deny the general validity of Bohmian mechanics (and other trajectory-based approaches) in providing a complete interpretation of quantum mechanics. Here, this assertion is overcome by means of a formal extension of Bohmian mechanics based on a limiting approach. Within this novel formulation, the particle dynamics is always satisfactorily described by a well-defined equation of motion. In particular, in the case of guidance under quantum fractals, the corresponding trajectories will also be fractal.”
Thanks - that clears everything up... ;)
I bet it was an indeterminant fracture until they took the x-ray.
I thought we were talking about quantum fractals here, LOL.
Yeah, no shit. First post I’ve never understood.
I had a Bohemian mechanic once and...
Oh, Bohmian.
Anybody want to drink beer and go four-wheelin’?
Bohemian Mechanical Rhapsody
Is this the real life?
Is this just fantasy?
Do objects have real states
Or just probabilities?
Open your eyes
Look up to the skies and see
Studying quantum (poor boy), I need no sympathy
Because I’m easy come, easy go
A little psi, little rho
No interpretation ever really matters to me, to me
Mama, just killed a cat
‘Least I think I might’ve did
Won’t know ‘til I lift the lid
Local realism was fun
But now I’ve gone and thrown it all away
Mama, ooo
Didn’t mean to make you cry
If I’m incoherent this time tomorrow
Calculate, calculate, as if nothing really matters
Too late, my state’s collapsed
Sends shivers down my spine
Decohering all the time
Goodbye determinism- you’ve got to go
Gotta leave you all behind for random chance
Einstein, ooo - (anyway the wind blows)
God should not play dice
I sometimes wish I’d never read Born at all
I see a little silhouetto of a psi
Scaramouche, scaramouche will you do the fandango
Action at a distance, very very spooky to me
Gallileo, Gallileo,
Gallileo, Gallileo,
Gallileo where’d you go? I don’t know (oh, oh, oh)
I’m just a physicist, nobody loves me
No information has speeds more than c
Spare all our brains from non-locality
Easy come easy go - will you let me go
Bell’s theorem! No - we will not let you go
let him go
Bell’s theorem! We will not let you go
let him clone
No cloning! We will not let you clone
let me go
Will not let you go
let me go (never)
Never let you go
let me go
Never let me go - ooo
No, no, no, no, no, no, no
Oh mama mia, mama mia, mama mia let me go
Heisenberg has a matrix put aside for me
for me
for meeeeeee
So you think you can stone me and spit in my eye
And then decohere me and collapse my psi
Oh baby - can’t do this to me baby
Just gotta get out - just gotta get right outta here
Ooh yeah, ooh yeah
Nothing really exists
When no-one can see
Nothing really exists - nothing really matters to me
Anyway the wind blows...
“Anybody want to drink beer and go four-wheelin’?”
I’m up for that.
Very good.
No doubt written by a physicist who (not surprisingly) had trouble getting a date....
In other words, the equations balance.
