An interesting discussion on the journal club of CMP: about the discovery of chiral Majorana zero modes in QAHI by K. Wang and S.C. Zhang
After the publication of this paper , about the signature of chiral Majorana zero modes in the quantum anomalous Hall insulator, Prof. Jason Alicea wrote a commentary on Journal Club for Condensed Matter Physics . However, Prof. Beenakker wrote another commentary to oppose this experiment, in which he cited two theoretical articles showing that the e 2 /2h does not need the presence of chiral Majorana modes. This argument is actually just recently confirmed by a recent experiment . It is always fun to read the discussions between physicists. Science evolves through them.
