SLAC researchers find evidence for quantum fluctuations near a quantum critical point in a superconductor
Theory suggests that quantum critical points may be analogous to black holes as places where all sorts of strange phenomena can exist in a quantum material. Now scientists are trying to pin down where this particular quantum critical point might be.
