PhysicsUltracold clocks could reveal how quantum physics alters time The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test the boundaries of physics ¿ìè¶ÌÊÓÆµ
PhysicsMaking atoms self-magnify reveals their quantum wave functions Trapping ultracold atoms with laser light let researchers magnify and then image the wave functions of atoms that were previously too close together to look like anything but a blob ¿ìè¶ÌÊÓÆµ
