Query: Ab initio simulation framework for Majorana transport in 2D materials:
  towards topological quantum computing   We present an ab initio modeling framework to simulate Majorana transport in
2D semiconducting materials, paving the way for topological qubits based on 2D
nanoribbons. By combining density-functional-theory and quantum transport
calculations, we show that the signature of Majorana bound states (MBSs) can be
found in 2D material systems as zero-energy modes with peaks in the local
density-of-states. The influence of spin-orbit coupling and external magnetic
fields on Majorana transport is studied for two relevant 2D materials, WSe2 and
PbI2. To illustrate the capabilities of the proposed ab initio platform, a
device structure capable of hosting MBSs is created from a PbI2 nanoribbon and
carefully investigated. These results are compared to InSb nanowires and used
to provide design guidelines for 2D topological qubits.
