A Super New Theory to Explain Superconductivity
By UNIVERSITY OF TSUKUBA JULY 10, 2021
Electricity Superconductivity Concept
A researcher at the University of Tsukuba introduces a new theoretical model of high-temperature superconductivity, in which electrical current can flow with zero resistance, which may lead to extremely efficient energy generation and transmission.
A scientist from the Division of Quantum Condensed Matter Physics at the University of Tsukuba has formulated a new theory of superconductivity. Based on the calculation of the “Berry connection,” this model helps explain new experimental results better than the current theory. The work may allow future electrical grids to send energy without losses.
Superconductors are fascinating materials that may look unremarkable at ambient conditions, but when cooled to very low temperatures, allow electrical current to flow with zero resistance. There are several obvious applications of superconductivity, such as lossless energy transmission, but the physics underlying this process is still not clearly understood. The established way of thinking about the transition from normal to superconducting is called the Bardeen-Cooper-Schrieffer (BCS) theory. In this model, as long as thermal excitations are kept small enough, particles can form “Cooper pairs” which travel together and resist scattering. However, the BCS model does not adequately explain all types of superconductors, which limits our ability to create more robust superconducting materials that work at room temperature.
Now, a scientist from the University of Tsukuba has come up with a new model for superconductivity that better reveals the physical principles. Instead of focusing on the pairing of charged particles, this new theory uses the mathematical tool called the “Berry connection.” This value computes a twisting of space where electrons travel. “In the standard BCS theory, the origin of superconductivity is electron pairing. In this theory, the supercurrent is identified as the dissipationless flow of the paired electrons, while single electrons still experience resistance,” Author Professor Hiroyasu Koizumi says.
As an illustration, Josephson junctions are formed when two superconductor layers are separated by a thin barrier made of normal metal or an insulator. Although widely used in high-precision magnetic field detectors and quantum computers, Josephson junctions also do not fit neatly the inside BCS theory. “In the new theory, the role of the electron pairing is to stabilize the Berry connection, as opposed to being the cause of superconductivity by itself, and the supercurrent is the flow of single and paired electrons generated due to the twisting of the space where electrons travel caused by the Berry connection,” Professor Koizumi says. Thus, this research may lead to advancements in quantum computing as well as energy conservation.

LOL...Yeah, Yeah, that’s the ticket...Anyway, as usual, you have posted an interesting article.
Gotcha.
Maybe that’s what’s happening with Hunter Biden?
It’s a little bit like how La Place came up with his La Place Transforms...
Having been sent to the back of the class when nonhomogeneous differential equations were being discussed, LaPlace was beyond me...LOL...so was algebra at times!
Just where do these clowns get off?
I would understand that is mean relative to existing low temp regimes. For example, conducting high current in the liquid nitrogen range would be a big step versus transmission using liquid helium. At the SSCL (Superconducting Super Collider Lab) in Texas (before premature termination), the power supplies were typically 10,000-15,000 amps at 7-10 VDC when using liquid HE. The Cu conduits resembled 2x6 boards!

relentless progress towards usable RTSC - room temperature superconductivity -
Well as this paper implies, the field of superconductivity is "heating up" these days ..literally
The prior story which may be very important on this point - and in the relentless progress towards usable RTSC - room temperature superconductivity - itself came out just a few weeks back
... which is a high pressure but ambient temp (non cryogenic) phenomenon... involving superhydrides ... which curiously could be related to LENR and the Mills/Holmlid effect, if as I suspect the superhydrides are found to be in highly redundant ground states (as an alternative to pressurization)
The holy grail of course would be a metal superhydride going into RTSC phase at ambient pressure.
This advance would revolutionized the economy in so may ways - it would be the "next big thing" as they say.
Does the "Berry phase" of this new theory help us to understand superhydride RTSC ?
It doesn't look that way so far. The whole thing could be little more than hype if it does not illuminate RTSC.
You have to worry when a PR firm releases a technical paper.
Thermacore and the missing link to the Kervran effect

A neglected paper and fringe theory, which may stand up to closer scrutiny,
appeared last year from Romania. It addresses the Kervran effect and the Mills
hydrino with a vortex model somewhat reminiscent of the recent “Berry”
superconductor theory.
https://medcraveonline.com/PAIJ/PAIJ-04-00204.pdf
The Kervran effect has an overlooked connection to one of the most convincing
experiments ever in LENR, involving the company Thermacore, Inc ... and their
work with Randell Mills plus the eventual patent nearly 30 years ago. The
important paper from that era has been removed from the BLP site: Thermacore,
Inc. “Final Report, SBIR Phase I, Nascent Hydrogen: An Energy Source.”
The Thermacore Patent, now expired, is 5,273,635 from 1993 Inventors: Gernert,
Shaubach, and Ernst Note: Randell Mills is NOT listed as co-inventor. Nor did
they mention the Kervran effect, but the did document a characteristic emission
line at 54.4 eV which Mills predicted. There was no radioactivity. One wonders
in hindsight if they would have found calcium after the year long run, should
they have looked.
Another missed opportunity?Consider this quote from Thermacore: “Light water
electrolytic experiments at Thermacore show positive results. The most
outstanding example is a cell producing 41 watts of heat with only 5 watts of
electrical input. The cell has operated continuously for over one year...” That
is a COP of 8, claimed by experts.
It bears repeating: THE CELL OPERATED CONTINUOUSLY FOR OVER ONE YEAR, and
remember, this statement is not coming from some fly-by-night self-promoting
entrepreneur, nor even university professors who are ignorant of manufacturing
realities - but instead it comes from one of the most well-respected of
high-tech firms in the World, in thermal engineering. This is the firm which
invented the heat-pipe and other related devices.
Yet it all came to naught. Go figure.
