      abstract     = {In the rapidly evolving field of condensed matter physics,
                      the study of topological insulators has opened new horizons
                      for understanding of quantum states of matter. Among these,
                      bismuth antimony telluride selenide (BSTS) materials stand
                      out due to their unique electronic properties and potential
                      applications in quantum computing. This thesis presents an
                      in-depth analysis of BSTS materials, focusing on the pivotal
                      role of spin-orbit coupling and compositional variations in
                      driving topological phase transitions of the [Bi x Sb (1-x)
                      ] 2 [Te y Se (1-y) ] 3 random alloy. Through sophisticated
                      computational models and simulations, we dissect the band
                      structures of BSTS materials to uncover the mechanisms that
                      govern their topological behaviors. Our research not only
                      advances the theoretical framework of topological insulators
                      but also paves the way for practical applications in
                      next-generation electronic devices, offering insights into
                      the exploitation of Majorana fermions and the enhancement of
                      superconducting properties. The findings of this thesis aim
                      to contribute substantially to the field of quantum
                      materials, highlighting the promise of BSTS materials in the
                      quest for new quantum phenomena and technologies.},
