scientist have proposed a theoretic means that light could be slack down to a complete block , using something anticipate “ exceeding degree ” .
publish inPhysical Review Letters , the writer describe in their subject how previous methods included using a swarm of ultracold particle of sodium to slow light down to velocity approaching zero , but not quite there .
Theirmethod , however , require using a waveguide – a body structure that guides waves in other words , like a tube – to make special point . These are realm where two complex wavelength patterns conform to and unify .
What does that think of precisely ? Well , we know that light is a wave ( most of the meter ) , and these moving ridge constantly alter their frame depending on what they ’re propel through .
AsLive Sciencenotes , if you tune up the properties of a container , you may collapse one of light ’s complex waves with its mirror Twin Falls . basically , they cancel each other out . And the point at which that happens is call an exceeding item .
“ In this work , we disclose the carnal knowledge of the stopped light effect with the phenomenon of [ the ] exceptional stage , ” the investigator , Tamar Goldzak and Nimrod Moiseyev from the Israel Institute of Technology and Alexei Mailybaev from the Institute for Pure and Applied Mathematics in Brazil , wrote in their paper .
especial points have been shown to have someweird physicsbefore , such as causing laser to switch on despite Energy Department apparently being taken away . send two undulation musical mode past an special point wasdescribedas “ driving a car into an frosty two - lane tunnel , in which one slither around wildly , but from which one always comes out on the right side of the route . ”
According to this latest paper , in theory , you could get balance beam of light to stop move completely at an prodigious point by changing their dimension . The light can then move again when the properties are change by reversal .
This inquiry is , the right way now , theoretic . But it could open up some interesting boulevard for so - called “ tiresome - light applications ” , utile for thing liketelecommunications . And the researchers enunciate the method acting could enforce not just to light waves , but other waves like strait too .
