<ul><li>Physicists have produced a new superconducting state which has modulation in energy gap at the atomic scale.</li><li>The new state, named Cooper-pair density modulation (PDM), has stronger energy gaps up to 40% in some areas in flakes of an iron-based superconductor.</li><li>This modulation is significant as it provides clearer evidence that energy gap modulation can exist at the atomic scale.</li><li>The discovery was made possible through successful scanning tunnelling microscopy of the iron-based superconductor.</li></ul>
