Retraction Note: Evidence for spin–charge separation in quasi-one-dimensional organic conductors

Nature 418, 614–617 (2002) In this Letter, we described the anomalous behaviour of the thermal conductivity k in quasi-one-dimensional Bechgaard salts. As we have since observed a conventional temperature dependence of k in another quasi-one-dimensional organic conductor, TTF-TCNQ, we remeasured thevalue of k in our Bechgaard salts and identified a heat leakage in the original experimental set-up, which becomes relevant for samples with very small values of k at low temperatures.
