Intelligent machines learn how to cool cold atomic clouds captured with laser beams

According to ANU's website, scientists at the University and the University of New South Wales (UNSW) use an online optimization program to teach a machine to learn how to cool a cold atomic cloud captured with a laser beam to become a Bose- Einstein Condensation (BEC) experiment of intelligent machines.

This smart machine is learning to simulate. The researchers refrigerated the gas to 1 mK (micro-degrees Kelvin) and handed it the right to control the three laser beams, allowing it to continue cooling the captured gas to the point where it was taken aback that it innovated a pattern of its own Making the laser energy used gradually reduced, and the resulting BEC higher quality. The paper, published in the journal Nature Science, explains that the intelligent machine simulates the relationship between parameters through a "Gaussian process" and ensures that the number of iterations required for the experiment is less than the best of the past 10 Times

Bose - Einstein condensate coldest in the universe, much colder than outer space, usually less than one billionth of an absolute zero. Because of their extreme sensitivity to external disturbances, they can be used to accurately detect small changes in geomagnetic field or gravity and have great potential in mineral prospecting and navigation. This intelligent machine system has growth capabilities that allow fragile BEC technology to perform its full potential in detecting field forces.

Australian Institute of Defense researcher Michael Hooih said that you can create a working device that measures gravity and put it in the trunk of a car, and the smart machine will readjust to keep it on its own, much more than hiring a physicist Follow you everywhere cheaper. "Next we intend to use it to help make a bigger Bose - Einstein condensate, believe it will be faster than ever before."

Paul Wegley of ANU Institute of Physics and Engineering also said he did not expect the machine to start from scratch and learned to experiment within an hour. If only a simple computer program to direct it to do the experiment, the time spent may be longer than the universe age.

Elbow Laser Cutting Machine

Elbow Laser Cutting Machine:
