Query: Strain induced spin vortex and Majorana Kramer's pairs in doped
  topological insulators with nematic superconductivity   Using Ginzburg-Landau approach we show that the strain of the nematic
superconductor can generate a specific (nematic) vorticity. In the case of
doped topological insulators that vorticity forms a spin vortex. We find two
types of topologically different spin vortices that either enhance (type I) or
suppress (type II) superconductivity far from the vortex core. We apply
Bogoliubov-de Geunnes equations to study electronic states in the nematic
superconductor with spin vortices. We find that in the case of the vortex of
type I, zero-energy states are localized near the vortex core. These states can
be identified as Majorana Kramer's pairs. In the case of the vortex of type II,
zero-energy states form Majorana flat bands. Thus, we establish a non-trivial
connection between the strain and Majorana fermions in the doped topological
insulators with nematic superconductivity.
