(Phys.org)—A team of researchers at Sandia Labs in the U.S. has developed a type of atom interferometer that does not require super-cooled temperatures. In their paper published the journal Physical Review Letters, the ...
Next-generation sensors to be used in fields as diverse as mineral exploration and climate change will be turbo boosted thanks to University of Queensland and University of Sussex research.
