Strange metals have baffled scientists since their discovery. Now, theorists have finally come up with an explanation.
Physicists have come up with a universal theory to explain how a group of bizarre metals behave, and it could aid the search for a room-temperature superconductor.

Physicists hoped this discovery would lead to finding room temperature superconductors — opening the door to the near-lossless transmission of electricity. Yet the discoveries petered out, and recent claims of room temperature superconductors have ended in scandal and disappointment. "We have entanglement between many electrons all at the same time, not just two in a pair. The system of electrons is 'quantum critical' — in a sense that means it's as entangled as it can possibly get," Patel said.
