Query: Nematicity in stripe ordered cuprates probed via resonant x-ray
  scattering   In underdoped cuprate superconductors, a rich competition occurs between
superconductivity and charge density wave (CDW) order. Whether rotational
symmetry breaking (nematicity) occurs intrinsically and generically or as a
consequence of other orders is under debate. Here we employ resonant x-ray
scattering in stripe-ordered (La,M)_2CuO_4 to probe the relationship between
electronic nematicity of the Cu 3d orbitals, structure of the (La,M)_2O_2
layers, and CDW order. We find distinct temperature dependences for the
structure of the (La,M)_2O_2 layers and the electronic nematicity of the CuO_2
planes, with only the latter being enhanced by the onset of CDW order. These
results identify electronic nematicity as an order parameter that is distinct
from a purely structural order parameter in underdoped striped cuprates.
