Universal Quantum Phenomenon Found in Strange Metals

Nov 19 2018

Sean Hartnoll offers insight on experiments suggesting that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit. 

“The experiments point to a tantalizing universality across materials, one that would involve a deep idea in quantum mechanics and statistical mechanics,” said Professor Hartnoll. The effort to pinpoint that deep idea has turned up surprising connections to black holes, gravity and quantum information theory.  [Read more.]
