Desert Air, by George Steinmetz #socialmedia #Earth's #beauty

Posted by George Steinmetz on September 28, 2012

 

"For the past fifteen years George has been working on a somewhat obsessive project to photograph all of the world's hyper arid regions. The idea came to him when he started flying his motorized paraglider over the Sahara in the late 90s, and has taken him to 27 countries plus Antarctica. What he found on this oddyssey was a collection of co-evolved landscapes, like a disparate family, with each desert having unique variations on the common dry-land features of sand dunes, salt lakes, and wind erosion. He also discovered the highly developed strategies that allow man, vegetation, and wildlife to endure on the outer limits of survival."

For the first time, scientists "squeeze" light one particle at a time #physics #science

For the first time, scientists "squeeze" light one particle at a time #physics #science | Limitless learning Universe | Scoop.it

A team of scientists has successfully measured particles of light being “squeezed”, in an experiment that had been written off in physics textbooks as impossible to observe.

 

Squeezing is a strange phenomenon of quantum physics. It creates a very specific form of light which is “low-noise” and is potentially useful in technology designed to pick up faint signals, such as the detection of gravitational waves.

 

The standard approach to squeezing light involves firing an intense laser beam at a material, usually a non-linear crystal, which produces the desired effect.

 

For more than 30 years, however, a theory has existed about another possible technique. This involves exciting a single atom with just a tiny amount of light. The theory states that the light scattered by this atom should, similarly, be squeezed.

 

Unfortunately, although the mathematical basis for this method – known as squeezing of resonance fluorescence – was drawn up in 1981, the experiment to observe it was so difficult that one established quantum physics textbook despairingly concludes: “It seems hopeless to measure it”.

 

So it has proven – until now. In the journal Nature, a team of physicists report that they have successfully demonstrated the squeezing of individual light particles, or photons, using an artificially constructed atom, known as a semiconductor quantum dot. Thanks to the enhanced optical properties of this system and the technique used to make the measurements, they were able to observe the light as it was scattered, and proved that it had indeed been squeezed.

 

Professor Mete Atature, from the Cavendish Laboratory, Department of Physics, and a Fellow of St John’s College at the University of Cambridge, led the research. He said: “It’s one of those cases of a fundamental question that theorists came up with, but which, after years of trying, people basically concluded it is impossible to see for real – if it’s there at all.”

 

“We managed to do it because we now have artificial atoms with optical properties that are superior to natural atoms. That meant we were able to reach the necessary conditions to observe this fundamental property of photons and prove that this odd phenomenon of squeezing really exists at the level of a single photon. It’s a very bizarre effect that goes completely against our senses and expectations about what photons should do.”
