      abstract     = {The quasiparticle interference (QPI) technique is a
                      powerful tool that allows to uncover the structure and
                      properties of electronic structure of a material combined
                      with scattering properties of defects at surfaces. Recently,
                      this technique has been pivotal in proving the unique
                      properties of the surface state of topological insulators
                      which manifests itself in the absence of backscattering.
                      Herein, a Green function‐based formalism is derived for
                      the ab initio computation of Fourier‐transformed QPI
                      images. The efficiency of the new implementation is shown at
                      the examples of QPI that forms around magnetic and
                      nonmagnetic defects at the Bi2Te3 surface. This method
                      allows a deepened understanding of the scattering properties
                      of topologically protected electrons off defects and is a
                      useful tool in the study of quantum materials in the
                      future.},
