Fig. 2: Two-component decomposition of the CDW order in LSCO.

a Integrated intensities for CDW_SRO and CDW_stripe extracted from the two-component fits. The brown dashed line shows the scaled SDW intensities measured by neutron scattering²³. b Corresponding peak width for CDW_SRO and CDW_stripe. The widths are fixed for T < T_c for the two-component fits, as described in the main text. c A pictorial illustration of the mixed phases in LSCO at low temperatures, which consist of superconducting regions with suppressed CDW_SRO, and separate regions dominated by spin-charge stripe order. d–f Representative data and corresponding fits at 6.5 K, 23 K, and 32 K, respectively. Orange, blue, and red dashed lines show the total, CDW_SRO, and CDW_stripe of the two-component fits, respectively. For comparison, the single-peak fits are shown in solid black lines. Blue and red shadings illustrate contributions from CDW_SRO and CDW_stripe, respectively. Error bars represent one standard deviation.
