Published 17 September 2026. Material: La1.675Eu0.2Sr0.125CuO4. Method: scanning three-dimensional X-ray diffraction.
What we use it for
Evidence for broad, spatially organized structural regions inside the measured material, including approximately 150 nm boundary widths at 300 K.
What it does not establish here
No independent validation of NetPhysics, no demonstrated physical memory and no direct local superconducting-response map at every boundary. Our conductivity model is illustrative.
