Publisher Correction: Quantum coherence of multiple excitons governs absorption cross-sections of PbS/CdS core/shell nanocrystals.

Abstract

The original version of this Article contained an error in the seventh sentence of the second paragraph of the 'TA amplitudes for double pump-pulse excitation" section of the Results, which incorrectly read 'The absorption cross-sections of the transitions from the single exciton state to the biexciton and triexciton states are denoted by σ' and σ'', respectively.' The correct version states 'σ''' in place of 'σ'''.The ninth and tenth sentences of the same paragraph originally incorrectly read 'The most important issue of this work is to clarify whether the multiple exciton absorption cross-sections σ' and σ'' are equal to σ or not. The black dotted curves in Fig. 3b, c show the predicted results of the TA amplitudes by assuming identical cross-sections, i.e., σ = σ ' = σ'' = .' The correct version states 'σ' and σ'' are equal" instead of 'σ' and σ'' are equal' and 'σ = σ' = σ''' in place of 'σ = σ ' = σ'' = '.This has been corrected in both the PDF and HTML versions of the Article.
