Something in Nothing
[ Issue 141 Page 2 ] Monday, November 09, 2015, 07:34:04 Dong Hwan Kim Junior Staff Reporter bingkong@kaist.ac.kr

Is there anything to observe in the vacuum, when the vacuum is the absolute nothingness? Or is it? Professor Alfred Leitenstorfer and his research team at the University of Konstanz in Germany succeeded in direct observation of vacuum fluctuation. Against the prevailing assumption to the contrary, the research team managed to directly detect vacuum fluctuations with high-precision electric fields. Due to its significance in the field of quantum mechanics, the demonstration will be published in the journal Science.

"We have had a few years of sometimes sleepless nights - all possibilities of potentially interfering signals had to be excluded," Leitenstorfer said. "All in all we found out that our access to elementary time scales, shorter than the oscillation period of the light waves we investigate, is the key to understand the surprising possibilities that our experiment opens up."
