Orbital symmetry of charge-density-wave order in La1.875Ba0.125CuO4 and YBa2Cu3O6.67

Resonant soft X-ray scattering characterization of the cuprate superconductors La1.875Ba0.125CuO4 and YBa2Cu3O6.67 shows that the orbital symmetry of the charge density waves is a key feature determining their properties.
