Metallic phase for bosons implies new state of matter graphic

STORY EMBARGOED FOR RELEASE UNTIL 1 P.M. CDT OCT. 9 (THURSDAY)

Phase diagram showing the destruction of superconductivity: 1) The yellow region represents the ordered phase in which all the electron pairs share the same phase (all arrows pointing up), 2) The elusive bose metal is in blue in which all the phases are disordered but form a glass, and 3)
Beyond the electron pairs fall apart and form an insulator. The vertical axis represents temperature and the in-plane axes any of the tuning parameters that destroy superconductivity such as defects or magnetic field.
