Article Synopsis
- The study uses NMR to observe a unique distribution of ^{17}O Knight shifts in YBa_{2}Cu_{3}O_{y} when superconductivity is disrupted by a magnetic field, leading to long-range charge-density-wave (CDW) order.
- This distribution is attributed to an uneven local density of states caused by quasiparticle scattering off unidentified defects within the CDW state.
- The results suggest a connection to quasiparticle bound states that can occur in certain metals and superconductors, highlighting the complex interactions within CDW materials and their sensitivity to disorder.
