Experiments suggest that exotic superconducting materials share a “strange metal” state characterized by a quantum speed limit that somehow acts as a fundamental organizing principle.
Strange metals are a type of material that exhibit unusual electrical and thermal properties at low temperatures. They are characterized by a linear relationship between temperature and resistivity, as well as a non-Fermi liquid behavior in their electronic structure.
Universal quantum phenomena in strange metals refer to the observation that these materials exhibit similar behaviors and properties across different systems and experimental conditions. This suggests the presence of a common underlying mechanism governing their behavior.
Strange metals are believed to be intimately connected to the mechanism of high-temperature superconductivity. The presence of universal quantum phenomena in both systems suggests a shared origin, and studying strange metals can provide insights into the behavior of high-temperature superconductors.
Some common experimental techniques used to study universal quantum phenomena in strange metals include transport measurements, angle-resolved photoemission spectroscopy (ARPES), and neutron scattering. These techniques allow scientists to probe the electronic and magnetic properties of the material and observe how they change with temperature and other external factors.
Understanding universal quantum phenomena in strange metals can have significant implications for the development of new materials and technologies. It can also help us better understand the behavior of other complex systems, such as high-temperature superconductors, and potentially lead to the discovery of new physical laws and principles.
