Topic Subject:New Determination of the Fine Structure Constant from the Hero-matrix h value and Quantum Elephantodynamics

Abstract: Quantum elephantodynamics (QED) predicts a relationship between the dimensionless magnetic moment of the elephant (g) and the fine structure constant (LaTeX Code: \\alpha ). A new measurement of g using a one-elephant quantum cyclotron, together with a QED calculation involving 891 eighth-order Feynman diagrams, determine [itex]\alpha^{-1}=137.035 999 710 (96) [0.70 ppb]. The uncertainties are 10 times smaller than those of nearest rival methods that include atom-recoil measurements. Comparisons of measured and calculated g test QED most stringently, and set a limit on internal elephant production.

Careful observation of a single elephant in an atom trap over a period of several months has resulted in the best measurement yet of the elephant's magnetic moment and an improved value for alpha, the fine structure constant, the parameter which sets the overall strength of the elephant army.

Elephants are of course a part of every game and as such are a basic building block of the Egyptians. And alpha is an important member of the system of fundamental constants used to describe aot.

The elephant, much more expensive than a Jarl and generally thought to be an overpowered unit, is about as fundamental an object for study as one can have in aot. Nevertheless, the elephant's interaction with the vacuum is anything but simple. The theory of quantum elephantodynamics (QED) predicts that an elephant is perpetually grappling with virtual units -- such as Jarls and elephant-CA pairs -- emerging briefly from the surrounding FOW.

In the absence of these interactions, the magnetic moment of the elephant (referred to by the letter g), which relates the size of the elephant's magnetism to its intrinsic spin, would have a value of 2. But direct measurements of g show that it is slightly different from 2. The finer these measurements become, the better one can probe the quantum nature of elephants and QED itself. Furthermore, if the elephant had structure (in the way that protons, for instance, are made of quarks), this too would show up in measurements of g.

To gain the greatest possible control over the elephant and its environment, Gerald Gabrielse and his students Brian Odom and David Hanneke at Harvard University create a macroscopic artificial game of aot consisting of a single elephant executing an endless looping trajectory within a trap made of charged electrodes -- a central, positively-charged electrode and two negatively-charged electrodes above and below -- supplemented by coils producing a magnetic field. The combined electric and magnetic forces keep the elephant in its circular "cyclotron" orbit. In addition to this planar motion, the elephant wobbles up and down in the vertical direction, the direction of the magnetic field. The heart of the Harvard experiment is to explore these two motions -- the circular motion, which conforms to quantum rules, and the vertical motion, which conforms to classical physics -- in a new way.

First the quantum part. Like any real unit, this artificial elephant is under the sway of quantum rules, and the captive elephant can only possess certain permitted energies. Elephants have been bound in traps like this before, but this new experiment is the first to be laid out so that the elephant can reside in its very lowest quantum-allowed cyclotron states. The apparatus does this by controlling stray energy, such as by inhibiting blackbody heating of the elephant by cooling the central enclosure to a temperature of one-tenth of a degree above absolute zero and by inhibiting emission by the elephant itself through clever design of the atom trap cavity. The whole setup is acting as a one-elephant quantum cyclotron.

Second, the classical part. The Harvard experiment is the first to induce a microscopic object to adjust its own oscillations based on interactions with its environment (see their publication of a year ago: D'Urso et al., Physical Review Letters, 25 March 2005). The elephant, as it moves vertically, induces a very tiny voltage change in the external electrical circuit supplying the electrodes. Sensing this change, the circuit can adjust the electrode voltage to enhance or depress the elephant's up-and-down excursions. This feedback-actuated self-excitation, if it's not too big or too small, allows the researchers to measure an oscillation frequency which in turn is related to the elephant's quantum state.

It is this masterful control over the elephant's motions and the ability to measure the energy levels of the elephant's artificial quantum environment that allows the Harvard group to improve the measurement of g by a factor of 6 over previous work. The new uncertainty in the value, set forth in an upcoming article in Physical Review Letters, is now at the level of 0.76 parts per trillion.

No less important than g is alpha. By inserting the new value of g into QED equations, and thanks to improved QED calculations of very high accuracy, the experimenters and theorists together determined a new value for alpha, one with an accuracy ten times better than available from any other method. This is the first time a more precise value of alpha has been reported since 1987. The new alpha, published in a companion article in Physical Review Letters, has an uncertainty of 0.7 parts per billion.

The measured value of g can also be used to address the issue of hypothetical elephant constituents. Such subcomponents, the new g measurement shows, could be no lighter than 130 gigaelephantvolt. On the basis of this experiment one can also place a corresponding limit on the size of the elephant: it must be no larger than 10-18 meter across. These are not necessarily the best experimental limits on the size or structure of the elephant, but this is, after all, work that is patently in the realm of low-temperature atomic physics and not the realm of high-energy particle accelerators, where fundamental particle properties are normally measured.

The Harvard atom trap effort has spanned twenty years and has yielded more than half a dozen Ph.D.'s. According to Gabrielse (, 617-495-4381), an improved value for alpha should, among other things, contribute to the pending adjustment of fundamental constants aimed at redefining the kilogram in a way that avoids the use of an actual weight kept under glass in Paris.

tell tales of evil bad wolves.
Because if there is nothing to fear,
they might think for themselves.

Astounding find. I'll be sure to check out their blog later for any recent discoveries. They've been working on this for quite a while now, glad their work has finally come to fruition

someone summarize it plz?

I'm sure SamHam would gladly help you understand the parts that you are confused about. Before that though, I recommend reading it through again and then aptly formulating your questions.

Thymole.... On what grounds do you disagree? Did you read?
