Universality of charge order in cuprate superconductors

22 diciembre 2014

Scientists have now identified charge order in HgBa2CuO4 , a pristine cuprate material. A further important result of the study is the finding that the charge order is closely related to quantum oscillations under a magnetic field. Finding a universal connection between the period of these quantum oscillations and the spatial period of the charge order is one of the achievements of the study.
