Amherst Researchers Create Magnetic Monopoles

timothy posted about 9 months ago | from the can-we-call-them-dirac's-revenge? dept.

Science 156

An anonymous reader writes "Nearly 85 years after pioneering theoretical physicist Paul Dirac predicted the possibility of their existence, an international collaboration led by Amherst College Physics Professor David S. Hall '91 and Aalto University (Finland) Academy Research Fellow Mikko Möttönen has created, identified and photographed synthetic magnetic monopoles in Hall's laboratory on the Amherst campus. The groundbreaking accomplishment paves the way for the detection of the particles in nature, which would be a revolutionary development comparable to the discovery of the electron." That's quite a step beyond detecting monopoles; the Nature abstract is online, but the full paper is paywalled.

Bullshit. Electric motors are limited by the performance of the conductors and the good old magnetic path where the monopoles are of no help. Electric motors with superconducting windings have been built, and they are pretty damn efficient. Heck, stock brushless electric motors are already pretty damn efficient.

Electric motors aren't getting more efficient until someone finds a better room-temperature conductor than copper. Ideally a superconductor. There's no fundamental law that says such a thing couldn't exist, but so far it has eluded all efforts to find one.

These are not actually Dirac monopoles. These are magnetic quasiparticles that behave in a way that simulates Dirac monopoles.

The Ars Technicha article has the best explanation:
http://arstechnica.com/science... [arstechnica.com]
Emphasis mine:
"Since we can't seem to find one, though, some researchers decided to emulate monopole behavior using an analogous quantum system. They used a Bose-Einstein condensate: a collection of very cold atoms that behaves like a single quantum system."

The U.S. Environmental Protection Agency (EPA)’s Energy Star program and Freddie Mac have signed an agreement that will help to cut carbon pollution while increasing the affordability of multifamily housing properties. The agreement outlines strategies to save water, energy and money for multifamily property owners and residents.

“Boosting energy and water efficiency not only saves money and makes these properties a better investment for owners and more affordable for families who live there -- it is also an important step in the President’s commitment to fighting climate change by cutting energy waste in our nation’s buildings,” said Janet McCabe, acting assistant administrator for EPA’s Office of Air and Radiation. “By making it easier to secure financing for energy efficiency investments and providing data about energy use and efficiency opportunities, these strategies will create lasting environmental and public health benefits while making multifamily buildings more efficient and valuable.”

"Freddie Mac is proud to partner with the EPA in this effort,” said Mitchell Resnick, Freddie Mac Multifamily vice president of loan pricing and securitization. “As one of the largest Commercial Mortgage-Backed Securities (CMBS) issuers in the country, we are looking to guide the industry and the CMBS market towards a greater sensitivity to environmentally responsible lending and investing. This partnership is the first of what we hope are many steps in that direction. We are looking at how energy efficiency improves the financial viability of the apartments we finance, and most importantly its impact on the affordability of rental housing."

Roughly one-third of Americans live in apartments within multifamily buildings, spending approximately $22 billion on energy every year. Rising energy costs are contributing to the decline in affordability for many of these Americans. Housing industry studies have projected that multifamily properties can become 30 percent more efficient by 2020, unlocking $9 billion in energy savings and preventing more than 35 million metric tons of greenhouse gas emissions per year.

In support of the President’s Climate Action Plan, this memorandum of understanding outlines key strategies to make multifamily housing more affordable by encouraging building owners and tenants to benchmark their energy and water performance and take steps to improve efficiency. Among those strategies:

- Freddie Mac will explore the collection of energy and water performance data from property owners during the loan underwriting and asset management processes.

- By demonstrating the financial value of energy and water efficiency to lenders and borrowers, Freddie Mac hopes to be able to influence lending practices in ways that encourage investments in energy efficiency and make multifamily housing units more affordable.

- EPA will assist Freddie Mac with these, and other, goals, by providing technical and educational support in the use of the Energy Star Portfolio Manager® energy management and tracking tool as well as other Energy Star resources.

The President’s Climate Action Plan calls for helping multifamily buildings cut waste and becoming at least 20 percent more energy efficient by 2020. While EPA has already been working with Fannie Mae and the U.S. Department of Housing and Urban Development, this latest agreement with Freddie Mac is another critical step forward in meeting the President’s goal. Together, these three organizations influence the largest sources of residential and multifamily lending in the country.

Products, homes and buildings that earn the ENERGY STAR label prevent greenhouse gas emissions by meeting strict energy efficiency requirements set by the U.S. EPA. In 2012 alone, Americans, with the help of ENERGY STAR, saved $26 billion on their utility bills and prevented greenhouse gas emissions equal to the annual electricity use from 35 million homes. From the first ENERGY STAR qualified computer in 1992, the ENERGY STAR label can now be found on products in more than 70 different categories, with more than 4.5 billion sold over the past 20 years. Over 1.4 million new homes and 20,000 office buildings, schools and hospitals have earned the ENERGY STAR label.

Re:Contradicts current theory? (4, Insightful)

tibit (1762298) | about 9 months ago | (#46110497)

That's some misunderstanding of what a scientific theory is, right there. A theory must have predictive power - it must be useful for something, that is. Electromagnetic theory, so far, is extremely successful precisely because it works where we need it to work. The monopole demonstration doesn't change it one iota - neither your computer nor your electric plant have stopped working overnight.

It doesn't matter in practice that it doesn't work everywhere, and there's no need to rewrite anything and there's no contradiction. We know that the classical theory of electromagnetism, well, applies to classical scale phenomena, under certain conditions. No scientist in their sane mind would insist that this effect contradicts the classical theory. It's simply outside of the classical theory's scope, just as relativistic effects are outside of the realm of classical mechanics.

The real problem is with extremely widespread, naive understanding of what a scientific theory is and that there are limits to applicability of any scientific theory of nature. The phrase "law of nature" is perhaps the biggest romanticism-imbued snafu there ever was in popularization of science.

Theory (due to Paul Dirac's work combining quantum mechanics and relativity in the first half of the 20th Century) had been predicting monopoles for a long time. Yeah, the simplified version that you were quoting from didn't predict monopoles, but the full version did. If the submitters of the paper have found one of these rare beasts in the lab, that's a very interesting confirmation.

The real question is whether the result can be reproduced by different experimenters in a different lab. (Since it's lab-scale work, that ought to be possible.) If so, watch out for some really interesting new areas of physics to be opened up.

It is trivial to add magnetic monopoles to Maxwell's equations. If anything, the equations become more symmetric and uniform with monopoles. They are normally left out because they had never been observed, so it would be like always plugging in a zero for the magnetic charge term.

Having dealt with a lot of over unity types at lab tours and from old contact emails, I don't see much if any correlation with a push for space programs from them. They are by far mostly too busy worrying about conspiracy theories or view government research as a problem and are not pushing for more. Those that discuss space travel are too busy using the past tense as if there are things already in progress and being hidden, or just assume it will be trivial given some other far out technology/psuedo-science they are focusing on instead. At least in that sense, their logic is sound: if we assume we have access to limitless power, space travel becomes a lot cheaper and straightforward. The problem is with the premise.

Re:Contradicts current theory? (2)

blueg3 (192743) | about 9 months ago | (#46110787)

No. Maxwell's equations are essentially symmetric with respect to electricity and magnetism. Not surprising, since they are really the same thing. The form that you usually learn in school reduces the equations by having magnetic charge = 0 and magnetic current = 0 everywhere, since as far as we know, that's the world we live in. But magnetic monopoles are in no way disruptive to our understanding of how electricity and magnetism work.

Re:Contradicts current theory? (4, Informative)

breech1 (137095) | about 9 months ago | (#46110969)

No it doesn't contradict previous theory. The existence of a magnetic monopole would require adding some extra terms in Maxwell's equations: one for magnetic "charge" (the monopole) and one for magnetic "current" (moving monopole) analogous to electric charge and current. (Adjusting Maxwell's equations this way is a popular exercise in advanced undergrad / grad level E&M courses). If your system happened to have a magnetic monopole in it, then you would need to use the equations with the extra terms. You would see some extra effects due to the monopoles, but they would be accounted for. The extra terms would give a nice symmetry to Maxwell's equations, helping to demonstrate that the electric and magnetic field are manifestations of the same phenomena (which isn't clear until you get to special relativity).

True. Also I thought I had seen this before from last year. Turns out I did.

So in other words, these are not the magnetic monopoles that were discussed learning Maxwells equations in Physics 201? Got it.

I always pictured a magnetic monopole to be spherical, with the flux eminating universally outward. And of course, with degradation over time.

I like the "electron hole" analogy. Electron holes aren't as spectacular as positrons; they don't annihilate electrons and generate gamma-ray photons. They can, however, "annihilate" an electron in a semiconductor to produce a visible photon -- and that's how we get LEDs.

This "monopole" won't let us build super-motors or disintegrate protons at will. But I wonder if, recreated in a more robust medium, it could have its own interesting uses?

Are these true really true monopoles? (2)

ArsenneLupin (766289) | about 9 months ago | (#46110713)

Or is it just like a normal, really long magnet with an "undetectable" body (the bar between the poles)?

Meaning, that if they have a south monopole somewhere in their "extremely cold gas", someplace else within the same gas has a north monopole. Then just consider the line linking both to be the magnet.

Call us back when they can separate them by splitting the "extremely cold gas" into 2 containers, in such a way that one container has the south pole, and the other the north pole, and both can be moved arbitrarily far from each other.

Glad they're back in stock... (3, Funny)

My previous supplier has left me high and dry and I can't finish my perpetual motion machine without one of these. Can I get a discount on more than one? Or do I have to buy them one by one to avoid them neutralizing each other?

"but the full paper is paywalled" (5, Insightful)

Unless you are really up on your Maxwell's equations and condensed matter physics, you wouldn't get much out of the actual paper. When I hear all the bitching and moaning about paywalled papers and how "the people" need to see the paper, I can't help but think that 99.999% of "the people" couldn't get past the intro paragraph because of all the field-specific details. That's why there are places like Scientific American and numerous science-writer blogs to translate this for the layman. If you can understand the following, then you most likely have access to the actual article, and if you don't know what this all means, then you are far better off going for the layman's summary:

The spinor order parameter corresponding to the Dirac monopole14,17 is generated by an adiabatic spin rotation in response to a time-varying magnetic field, B(r, t). Similar spin rotations have been used to create multiply quantized vortices18 and skyrmion spin textures19. The order parameter Y(r, t)5y(r, t)f(r, t) is the product of a scalar order parameter, y, and a spinor, f~ðfz1,f0,f{1T¼^ jfi, where fm5Æmjfæ represents the mth spinor component along z. The condensate is initially spin-polarized along the z axis, that is, f5(1, 0, 0)T. Following the method introduced in ref. 14, a magnetic field Bðr,t~bqðxx^zy^y{2z^zzBzðt^z is applied, where bq.0 is the strength of a quadrupole field gradient and Bz(t) is a uniform bias field. The magnetic field zero is initially located on the z axis at z~Bzð0=(2bq)?Z, where Z is the axial Thomas–Fermi radius of the condensate. The spin rotation occurs as Bz is reduced, drawing the magnetic field zero into the region occupied by the superfluid.

And half the time people complain that an article is pay-walled, they don't do a simple search for the article's title that would show a free preprint version as the first result. In this case, I don't see the article on places like ArXiV, but the authors have previous papers there so it only might be a matter of time before they upload it and/or update their website.

QED, not maxwells equations and yes part of my degree was the CMP. Anyway, the the subject of these articles are not monopoles at all, no magnetic field at all in fact, an imaginary compass wouldn't point toward them.

There is not one shred of evidence that magnetic monopoles exist. These researchers have not made a magnetic monopole.

Somewhere, sitting in the USPTO, signing off on useless "Do X on the Internet" patents, there is an individual for whom all of this stuff is trivially simple. We would do science a great service to facilitate this person's access to such material.

Even if only to provide a distraction and keep a number of useless patents off the books.

This!

The AC OP's point is a terrible one because it could apply to nearly everything more complicated than a primetime tv show. It isn't about the 99.999% who can't use the information, it is the 0.001% who can use it that matter and it is no one's job to decide who qualifies.

not really monopoles! (2)

You should be thanking Alan Guth and the Gods of Inflation they didn't find actual monopoles. Those things are terrifying beasts! They eat protons like it's going out of style!
