Negligence in Nature article on Quantized Majorana conductance

In the 2018 Nature article Quantized Majorana conductance , the first author involved, Dr Hao Zhang, and corresponding author, Professor Leo Kouwenhoven, were partly negligent and partly culpably negligent. There was no violation of scientific integrity. This is the judgement of the Executive Board of TU Delft, based on recommendations of the TU Delft Research Integrity Committee (CWI), supported by external experts, and advice of the Netherlands Board on Research Integrity (LOWI). Article withdrawn. A CWI investigation into the publication was initiated in 2020, after the authors were alerted to issues by two researchers in the field and re-examined their earlier findings. They found that the main conclusion had been insufficiently substantiated and withdrew the article. The CWI requested a number of independent international experts to look at the matter.
