In a new scientific precedent, a team of scientists at the University of Oxford announced the development of a computer simulation tool capable of tracking light interactions in the quantitative vacuum, moment by moment, in 3 dimensions and unprecedented accuracy. This has been published the study In the “Communichex” patrol of the “Nature” group.
The study reveals the truth of “nothingness” in the physical sense (not philosophical), where Zixen Zang, a researcher in the Department of Atomic Physics and Laser, says at the University of Oxford in statements to Al -Jazeera Net: “In daily terms, we believe that nothingness is an empty space, but in quantitative physics,” nothing “is not really empty,” adding: “Even in an ideal vacuum, there are small and rapid fluctuations It leads to the appearance of virtual particles that appear and disappear very quickly to the extent that it is difficult to monitor directly. “
Although these quantum phenomena have always been present in theories, the experimental tools for their monitoring remained limited. But the super -strength laser currently used to interact with this quantum vacuum, and monitor its indirect effects, such as changing light pulse properties that pass through.
The truth of the emptiness
The study offers a new simulation tool based on a model that describes how the quantum void affects light. “We have presented in our study a new simulation tool that enables to track how the laser pulses interact with the quantum vacuum. Our results show the reproduction of known phenomena such as duplication in the vacuum (where light changes due to the vacuum) and mixes the four waves (where a new light is generated from the overlapping of three light pulses), which confirms that the model works accurately and can help us in exploring more physics In the future. “
In the past, the models trying to simulate this reaction depended on inaccurate assumptions, such as considering the laser a perfect and regular wave, while the real laser is more complicated. Also, the old simulation tools were very slow or did not show sufficient details. “So we resort to digital simulation, but it is very expensive, especially in 3 dimensions.”
Here came the idea of the new tool: similar to a “high -speed camera” that picks up what is happening during the reaction, and the details show clearly and at a lower computer cost, Zang says: “The current simulation tools are either very slow, or do not show what is happening inside the interaction area. As for our new tools, it is more like a high -speed camera that allows watching the reaction moment by moment, which gives us a much deeper understanding.”
This tool has been developed within an environment called “Osiris”, and it has been modified so that it works highly efficiently using simple resources, which will help scientists explore more exotic physical phenomena in the future.
Not a reflection or union!
One of the amazing manifestations revealed by the simulation is that the void in the light of the heavy light behaves as if it changes its behavior towards the light, when the intensity of the light increases to it, which allows light interactions that are usually not possible.
Zang, and explains, “What is surprising is that light phenomena such as duplication or the mixing of the four waves, which usually need special materials, can occur here in the complete absence of any substance. All we need is a high vacuum and light density.”
This means that the new light pulse resulting from mixing the four waves is not a reflection of the three pulses, nor just a direct union between them, but rather a special interaction that occurs within the “nothingness” or the quantitative vacuum when these impulses intersect together.
This shift in the perception of emptiness also has practical effects, especially in designing future experiences in giant laser facilities, and Zang explains: “Our tools are available upon request and can simulate any laser preparation. This means that researchers in new facilities can test their ideas on the computer before they are actually implemented, and compare the results with what we produce in theory,” noting that the tool also supports alternative physical models.
The tool also allows to follow the exact time to reach optical impulses to detection devices, which is decisive for experiments that use high allergies that depend on timing. Most of the previous models do not specify when the reference will reach the detector. As for the new tool, it follows the development of the pulse, moment by moment, allowing accurate prediction of the time of the reference, and thus improving the effectiveness of experiments, according to Zang.
Molder
In one of the most important results of the study, the simulation revealed that the resulting pulse in the experience of mixing the four waves is directly affected directly the form of the overlap between the laser pulses entering. “The basic idea is that the resulting light is formed only in the area where the laser densities intersect. If the area is irregular, the outside pulse reflects this shape, as if it is a piece of biscuit that takes the shape of the mold. Our simulations have shown this interconnection clearly.”
Researchers aspire to become the basis for a broader tools to simulate the quantitative vacuum, not only in a complete vacuum but even when there are particles, which opens the door to simulating complex experiences. Thus, the vacuum is not just an absence of the material, but rather a square filled with the hustle and bustle of quantity physics and will not stop it in the coming years, as it witnesses accurate and complex light interactions that can now be, thanks to this simulation, watch it with unprecedented details.
