Thread: Electromagnetic 'Swamps'

This unusual behavior, called tunneling, is the particle equivalent of a person being able to walk through rather than over a mountain. The particle behavior is also one of the most common signs that everyday physics has broken down and quantum mechanics now controls the system

In their experiment, the scientists were looking for signs of resonant tunneling, where the electrons hop onto the carbon nanotube on their way between the two electrical leads in the system. "Tunneling is like jumping across a creek," he said, adding that resonant tunneling is where "you have a small island, the resonant level inside the nanotube, to briefly plant your foot."

The team created an energy-draining environment in the leads and then measured how easily the electrons moved through the resonant level in the nanotube at ultra-low temperature. At the leads, "it's like the banks of the creek are swampy, so it takes energy to push yourself for a jump," said Finkelstein, who led the study.

If the resonant 'island' is positioned right between the two 'banks', then the electrons can easily hop between the banks. But if the island is closer to one of the banks, the electrons stay tied to either one of the leads. This difference in behavior, which was unexpected, signals a quantum phase transition, Finkelstein said.

The discovery might not make it into technology any time soon

i called it a resonant energy transfer at the synaptic junction.


nice to see there is 'evidence' to be had, in a current form.

now they should check to see which materials will allow which wavelengths, then in which temp?



them dudes need to take with these dudes (dudettes, of course)

University of Arkansas scientists Sergey Prosandeev and Laurent Bellaiche, with A. Akbarzadeh of Rice University, Eric Walter of the College of William and Mary and A. Al-Barakaty of Umm Al-Qura University in Makkah, Saudi Arabia report their findings in Physical Review Letters.

You can find the materials known as relaxors in many everyday appliances, in life-saving heart implants and in most sensors. But despite their wide use, "we still didn't have a realistic theory of how these things work," Prosandeev said.

Transitions in the polarity of relaxors seem disorderly, which would make them difficult to control. However, Prosandeev and his colleagues wondered if order might lie beneath the disorder.

The researchers performed calculations on a certain type of relaxor, barium zirconium titanium oxide, Ba(Zr,Ti)O3. They found that the relaxor stopped being polarized at higher temperatures. Meanwhile, the material developed nanoregions with the same polarities at lower temperatures. They also showed that this happens because of competition between opposite effects, such as differences in the way titanium ions and zirconium ions want to move or stay in non-polar positions. Another struggle between opposites involves ferroelectric interactions at short distances versus antiferroelectric interactions at larger distances between the titanium atoms. At low temperatures, the changes in position of titanium atoms are parallel to each other within small polar nanoregions. At higher temperatures, the changes in position of titanium atoms are mostly random, which make the polarity disappear.

The researchers also resolved a long-standing controversy about the role of these random polar nanoregions in relaxors. Using their model, they could switch off and on the random fields and examine their effect on the properties of the material. They found that, contrary to what scientists thought previously, turning off random fields did not affect the relaxor's behavior at different temperatures.

Understanding these properties will allow researchers better control over the materials' properties, which will in turn make for better materials for everyday life

It's interesting to "think" about "thought" as a quantum level phenomena. At the deepest levels (or at least, at a VERY deep level), the quantum world dictates the neurotransmitters' modulation of inter-neural ionic conduction pathways. When we say "I have decided such and such..." the quantum activities that went into that so-called "decision" make the whole notion of "me deciding this and that" just a little less impressive than when we imagine that there really is some "me" beyond such non-local and extremely statistical phenomena.

the decision is focused and of a coherance. Kind of like writing, to convey a point

not much of a just a site rendition but more like within the coherance of the total of states.

ie.. memories are all over

I don't see how you can say that this is "a resonant energy transfer at the synaptic junction" when none of the molecules tested are the same ones that are used in our synapses function.

Thanks for the science daily link Bishadi,looks like a cool site.

the resonant energy transfer is the analogy of the process and can reprsent most any conveyance of energy across most any mass

idiots just dont see that.


morons will claim, that the mass is moving across the junction, versus the energy conveying across.

Kind of like the radio transmitter aint moving the signal to the radio antenna, the signal is the light. (resonant)

do you think i answered his question and he is formulating a response?
