Query: Majorana bound states in topological insulators with hidden Dirac points   We address the issue whether it is possible to generate Majorana bound states
at the magnetic-superconducting interface in two-dimensional topological
insulators with hidden Dirac points in the spectrum. In this case, the Dirac
point of edge states is located at the energies of the bulk states such that
two types of states are strongly hybridized. Here, we show that well-defined
Majorana bound states can be obtained even in materials with hidden Dirac point
provided that the width of the magnetic strip is chosen to be comparable with
the localization length of the edge states. The obtained topological phase
diagram allows one to extract precisely the position of the Dirac point in the
spectrum. In addition to standard zero-bias peak features caused by Majorana
bound states in transport experiments, we propose to supplement future
experiments with measurements of charge and spin polarization. In particular,
we demonstrate that both observables flip their signs at the topological phase
transition, thus, providing an independent signature of the presence of
topological superconductivity. All features remain stable against substantially
strong disorder.
