Spontaneous symmetry breaking by charge stripes in the high-pressure phase of superconducting La(1.875)Ba(0.125)CuO(4)

M. Huecker, M. v. Zimmermann, M. Debessai +3

In those cases where charge stripe order has been observed in cuprates, the crystal structure is such that the average rotational symmetry of the CuO2 planes is reduced from four-f…
