Recently, the group led by BAQIS adjunct scientist Prof. Jian Wang (Peking University), in collaboration with Prof. Ziqiang Wang’s group at Boston College, discovered MZMs at both ends of 1D atomic line defects in two-dimensional (2D) iron-based high-temperature superconductors and provided a promising platform to detect topological zero-energy excitations at a higher operating temperature and under zero external magnetic field.

Xi Lin and X. C. Xie from Peking University, associated with Beijing Academy of Quantum Information Sciences, reported their work on a 3/2 even-denominator fractional quantum Hall plateau on [Nature Communications] in 09/2019. They have observed a 3/2 FQH plateau in a single-layer 2DEG with lateral confinement at a bulk filling factor of 5/3, which suggests a tunneling conductance of 1/6 e^2/h.
