dc.descriptionWe study the electronic structure near impurities in the one-dimensional chains of YBa$_2$Cu$_3$O$_{6+x}$. Assuming chain superconductivity below $T_c$ due to a proximity coupling, we show that only a magnetic impurity induces resonance states in the local density of states. Its spatial structure reflects the particle-hole nature of chain superconductivity and thus distinguishes it from other broken symmetry phases. For a sufficiently large scattering strength, or due to interference effects arising from a second impurity, the chains undergo a quantum phase transition to a polarized state.
