Competing pair density wave and uniform <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>d</mml:mi> </mml:math> -wave superconductivity in phase-separated 214 cuprates at the 1/8 anomaly
Why does superconductivity weaken at 1/8 doping in cuprates? The authors reveal a hidden rivalry: a striped pair density wave (PDW) competes with uniform superconductivity. By tuning the crystal structure with Nd doping, they show how stabilizing the PDW state suppresses three-dimensional superconductivity, casting the ``1/8 anomaly'' as a signature of quantum phase competition.
