Physicists create a bizarre new quantum state called a fractional fermi sea

Physicists have discovered a strange new state of quantum matter in which ultracold atoms defy familiar organizational rules, forming a highly excited yet surprisingly orderly configuration called a "fractional Fermi sea. " The discovery challenges established quantum theories and hints at exotic...
