Greek Researchers Find Quantum Femto-Magnetism



dccs-300x155Greek scientists from the University of Crete and the Foundation for Research and Technology-Hellas (FORTH), in collaboration with U.S. scientists from Ames Research Center of NASA, have discovered a new way to create small magnets by using short laser light pulses. Thanks to quantum “games” with light, computers and other devices can become extremely quicker.

The discovery of the phenomenon that is called Quantum Femto-Magnetism was made by the University of Crete physics professor Ilias Perakis and his group in Greece, in co-operation with Ames Laboratory and Iowa State University physicist Jigang Wang and his team in the USA. It was  published in the April 4 issue of the internationally well-known Nature magazine.

The new research opens the door to create devices that will function 1,000 times faster, with at least 10 terahertz (1012 hertz) memory speeds instead of 10 gigahertz (109 hertz) as it happens today.

The researchers demonstrated experimentally that a magnetic structure can be changed within quadrillionths of a second (femtosecond) by using ultra-short laser pulses. They observed a transition from anti-ferromagnetic to ferromagnetic ordering in colossal magneto-resistive materials, which are promising for use in next-generation RAM memory, hard disk, and logic devices, as reported in FORTH’s website. They were able to magnetize the material 1000 times faster than the fastest current magnetic memories.

“A challenge facing magnetic writing, reading, storing, and computing is speed. Technology demands that the speed of electronic devices must increase by several orders of magnitude. We showed that we can meet the challenge to make magnetic switches think ultrafast, in the femtosecond–quadrillionths of a second– range by using quantum ‘tricks’ with ultrashort laser pulses,” Perakis and Wang said.

The experiments were performed at Ames Laboratory and Iowa State University. The theory that interprets the experiments was developed at the University of Crete and the Institute of Electronic Structure and Laser Foundation of FORTH in Greece.

“Our strategy and concept is to use all-optical quantum methods to achieve magnetic switching and to control magnetism. This lays the groundwork for seeking the ultimate switching speed and capabilities of CMR materials, a question that underlies the entire field of spin-electronics,” Perakis and Wang pointed out.

They added: “Our hope is that this means someday we will be able to create devices that can read and write information faster than ever before. The role of physics is to open new directions for technology. And our discovery of Quantum Femto-Magnetism may have just opened a new one.”

  1. These are the sort of Greeks we need. Scientists and producers.

    Communist welfare queens please move to your communist Eutopia of North Korea to see what your “democratic” system really stands for.

  2. right wing welfare queens like your friends on wall street have received more welfare than has been paid out in Greece EVER multiple times over. It’s actually funny that Greece will become like North Korea if the XA nazis ever get full control and their wish to instill another military dictatorship, like in north korea. oh the irony of your examples.

  3. Sure buddy. Its you calling for government services and spending for yourself and the rightwing are “welfare queens”. (oh… and the EU are “Fascists” according to you too)

    You keep ranting about XA to me when I am not an XA supporter you idiot.

  4. nope don’t think so. i never once called for government services and spending you dirty lying fascist. oh so are the trillions and trillions wall street has gotten from various financing mechanisms from world wide central banks not welfare? it’s pure and utter capitalism right? you might not be but you always defend them and call them patriots and gloss over the fact that they are nothing but low life nazi remnants from the security battalion and junta days

  5. You are the liar. First you slander me as “fascist” (along with EU and wallstreet) when I am pro-democracy and against racism.

    You even lie to yourself. Your anti-captalists “fascist” rants are implicitely demands for HANDOUTS for yourself. You are just too ashamed to admit it so you concoct fanciful fantasies that you are doing it for someone else (why you obsess over GD and illegals) You are a shameless parasite.that cares for nothing but yourself.. (and certainly in no shape or form a patriot)

  6. it’s not slander if it’s true my little fascist. which handouts again have i advocated for vs you who has no problem for 40 trillion + IN HANDOUTS FOR WALL STREET. hahahahaha the wall street sheep and muppet talking about patriotism when his (alex the prodoti) allegiance is to the parasitic non-value creating money masters. ok you low life fascist continue to praise those who have destroyed Greece.

  7. I am not praising those who have destroyed Greece. It is the endless demands from money from the state that is destroying Greece. (rather than focusing on business) It is those that lobby for 3rd world illegals with few prospects of integrating that are destroying Greece (rather than unapologetically defending our borders). It is the cowards that lobby for Skopians that are destroying Greece.

    IN other words… low life far leftist scum like you that shameless demand others feed you.

  8. No one here believes you are a patriot when you spend all your energies attack patriots rather than defending our homeland.

  9. LOLLLLLLLLLLLLLLLL THE HEAD PRODOTI FASCIST HAS SPOKEN. ALL BOW DOWN TO ALEX THE PRODOTI AND HIS OVERLORDS AT THE EU AND WALL STREET. i’m hardly leftist you fascist low life pig. and no my little fascist nazi, it is the EU and Wall street, whom you support and refuse to call them fascist because that would make you one which you are, that is destroying Greece. your lying fascist kolo even admitted that you know illegals and skopians are not the problem, YET for the millionth time you mention that they are destroying Greece. wrong again my little pos. it is the EU and Wall st that has destroyed Greece which has de-levered Greece’s ability to deal with illegals and this Skopian issue you obsess about.

  10. yes and you have sooooo many friends around here you dirty fascist. i’m heartbroken that you say I don’t have internet imaginary friends that tell me i’m a patriot. the only people who like your comments are XA nazis and their nazi friends in such euro white supremacist groups such as Freies Netz Süd. you are certainly not a patriot as you bow down to Samaras, the EU, and Wall St. avte gamisou PRODOTIIIIIIIIIIIIIIIIIIIIII

  11. Right right. I’m a fascist. EU is fsacist. US is fascist. Everyone is a fasicst… except the guy whose slandering eveyone that disagrees with him as as “fascist”

    Neither the EU nor Wall St. have anything to do with Greece’s predicament. Other countries are doing quite fine you scapegoating fanatic. Gfreece’s economic problems are fault of Greece. If we wish to fix them, WE OURSELVES must fix them, not blame foreign countries for them. (like fanatics like you do)

  12. According to polls 46 percent of Greeks think Samaras is the best leader we currently have no matter what you personally think.

    What “Friends’ do you think you think you have? Savas that wants to murder 15 percent of the Greek population, supports a party that colludes with Skopians, calls the christian orthodox religion “fascist”, and supports illegal immigration? With “Friends’ like that who needs enemies.

  13. FYI, the main reason this country is in hell is because Greeks have been divided and playing games upon another since antiquity, no surprise this is evident while reading through the comments as well. Well done prof. Perakis, you’ve been through a lot trying to face the Greek madness and pathogeny. As regards to you political-supporters go and troll somewhere else. There is plenty of cyber space where you can curse each other
