Abstract = {{Charge order in underdoped and optimally doped high-T-c superconductors
   Bi2Sr2-xLaxCuO6+delta (Bi2201) is investigated by Cu L-3 edge resonant
   inelastic x-ray scattering. We have directly observed charge density
   modulation in the optimally doped Bi2201 at momentum transfer Q(parallel
   to) similar or equal to 0.23 reciprocal lattice units, with smaller
   intensity and correlation length with respect to the underdoped sample.
   This demonstrates the short-range charge order in Bi2201 persists up to
   optimal doping, as in other hole-doped cuprates. We explored the nodal
   (diagonal) direction and found no charge order peak, confirming that
   charge density modulates only along the Cu-O bond directions. We
   measured the out-of-plane dependence of charge order, finding a flat
   response and no maxima at half integer L values. This suggests there is
   no out-of-plane phase correlation in single layer Bi2201, at variance
   from YBa2Cu3O6+x and La2-x(Ba,Sr)(x)CuO4. Combining our results with
   data from the literature we assess that charge order in Bi2201 exists in
   a large doping range across the phase diagram, i.e., 0.07 less than or
   similar to p less than or similar to 0.16, demonstrating thereby that it
   is intimately entangled with the antiferromagnetic background, the
   pseudogap, and superconductivity.}},
