Query: Spin Texture as Polarization Fingerprint of Halide Perovskites   Halide perovskites are perceived to be the promising class of materials for
optoelectronics, spinorbitronics and topological electronics due to presence of
strong spin-orbit coupling and polarized field. Here, we develop a Hamiltonian
using quasi-degenerate perturbation theory to describe polarized field driven
band structures and unique topological phases such as Dirac semimetallic rings
for the universal class of Halide perovskites including both inorganic and
hybrid members. The spin textures obtained through this theoretical model
captures minute effects of polarization and hence can be used as a modern tool
to determine the polarized field directions which have significant influence on
spinorbitronics. The analysis brings out the concepts of hybrid spin textures
intermixing the effects of valence and conduction bands under topological
quantum phase transitions, and spin texture binaries where alignment of the
spins are reversed between domains in the momentum space with sharp boundaries.
The results are validated through density functional calculations.
