Ghiringhelli The already overcrowded phase diagram of cuprate superconductors has recently accommodated a region characterized by incommensurate charge density waves (CDW), partly overlapping with superconductivity, and included in the pseudogap regime. Although charge order is strengthened by high magnetic fields and competes with superconductivity, its role in Cooper pairing is still unassessed, calling for more complete characterization in different families of cuprates. The authors present an extensive x-ray scattering study of charge order in single layer La-doped Bi2201, and they show it extends up to optimal-doping (OP33K, p =0.16) in this family too. The CDW peak sharpens at T c and disappears above the pseudogap onset at temperature T * . They also demonstrate that in the underdoped sample (OD15K, p =0.115) the charge density wave has no out-of-plane correlation and has dominant unidirectional nature within the planes. [Phys. Rev.
