Baby, it's cold inside: Scientists measure the universe's coldest stuff

Researchers who were not part of the project said they were impressed.

“It will be significant progress in the physics research of cold atoms if it can be verified,” Yifu Zhu, who teaches atomic, molecular physics and optics at Florida International University, told

Matter with a Bose-Einstein condensation state was observed in 1995, for which Eric A. Cornell, Wolfgang Ketterle and Carl E. Wieman were awarded the Nobel Prize in Physics in 2001.

“You increase the temperature of the atoms when you try to observe them, which means that it is difficult to see them and keep their temperature super-cold at the same time,” Zhu said. “The reported theoretical proposal may make it possible to observe the cold atoms and at the same time, not disturb their states.”

Though it is still very early in the research, it is likely the technique will make a significant contribution to atomic science, Dominik Schneble, a professor of physics at Stony Brook University in New York, said.
