发帖数: 375 | 1 How the other half cools. Four years ago, researchers cooled rubidium atoms into a quantum-mechanical superparticle called the Bose-Einstein condensate, a stunning feat lauded as Molecule of the Year in 1995 (Science, 22 December 1995, p. 1902). This year, physicists at the same lab knocked over another milestone, cooling a vapor of ornery atoms in the first step toward creating an even more bizarre macroscopic quantum state.
Every particle of matter comes in one of two types: bosons and fermion |
