Through the Looking Glass

“Canadian and international scientists have announced a major breakthrough in their ability to capture and store minuscule particles of antimatter, the mysterious substance described as a mirror image of everyday reality. It lies at the heart of the most fundamental questions in physics.

‘I call this a game-changer,’ said Makoto Fujiwara, a University of Calgary scientist and the lead author of a paper published in the journal Nature Physics.

‘The antimatter world is some sort of mirror world,’ he said.

‘We’re really peeking. There’s so many things were thought of as science fiction that we can seriously consider scientifically studying them. We’re really excited about this.'”

“The findings can be summarized as follows. (1) We have demonstrated confinement of antihydrogen atoms for 1,000 s. Our calculations show that these atoms are very probably in the atomic ground state after ~1 s, providing the first indication that anti-atoms have been prepared in the ground state, as required for precision spectroscopy. (2) From the distributions of annihilations in time and position of the released anti-atoms, information on the kinetic-energy distribution of the trapped antihydrogen was obtained for the first time. Our data are consistent with a model in which antihydrogen is produced from antiprotons thermalized in a positron plasma. Furthermore, from our detailed simulation studies, several features of trapping dynamics have been identified, including the possibility of measuring anisotropic energy distributions.”
