Making the strange metal state in even stranger
Researchers from Chalmers University of Technology, Sweden, have uncovered a striking new behavior of the “strange metal” state of high temperature superconductors. The discovery represents an important piece of the puzzle for understanding these materials, and the findings have been published in the highly prestigious journal Science

“Through novel experiments, we have learned crucial new information about how the strange metal state works” says Floriana Lombardi, Professor at the Quantum Device Physics Laboratory at the Department of Microtechnology and Nanoscience at Chalmers. © Chalmers
“Such a simple behaviour begs for a simple explanation based on a powerful principle, and for this type of quantum materials the principle is believed to be quantum entanglement.” says Ulf Gran, Professor at the Division of Subatomic, High-Energy and Plasma Physics at the Department of Physics at Chalmers. © Chalmers
