Phase diagrams show the conditions at which solid, liquid, and gas phases of a material may coexist or occur alone. Phase diagrams can also be drawn for solid-state materials to illustrate the intersections of different electronic, magnetic, or structural phases. By studying temperature- and stress-dependent transitions between metallic and insulating states in vanadium dioxide, a group led by David H. Cobden of the University of Washington, Seattle, has now identified the first . . .
