The dynamics and transport of a particle in condensed-matter systems can be described using a tight-binding Hamiltonian. In this work, we present a simple approach to investigate Anderson localization in a three-dimensional system with an off-diagonal disorder. We construct the tight-binding Hamiltonian for the system in which a single random energy is assigned to each lattice site, and the hopping integrals are restricted to nearest-neighbour sites only.\u00a0 We introduce bond-breaking disorder, where some hopping terms between sites are randomly weakened. We compute disorder-impacted density of states (DOS), the inverse participation ratio (IPR), and level statistics to identify the Anderson transition. Emergence of mobility edge has been seen while analysing inverse participation ratio with disorder.\u00a0 We address our problem in the thermodynamic limit by applying appropriate periodic boundary conditions and numerically demonstrate the existence of an Anderson localization transition.<\/span><\/p>

\u00a0Our research investigates Anderson localization in disordered systems, focusing on the effects of bond-breaking disorder. Anderson localization, where the electronic wavefunctions localize due to disorder, plays a key role in understanding electronic transport properties in various materials. In this study, we explore the specific case of bond-breaking disorder, where random changes in bond strengths can disrupt the structure of the system, leading to alterations in the electronic states and transport behavior.<\/span><\/p>

We have demonstrated the Anderson transition \u2014 the shift from extended to localized electronic states \u2014 using two powerful techniques: the Inverse Participation Ratio (IPR) and level statistics. By analyzing the IPR, we identified the critical disorder strength that marks the localization transition. Furthermore, level statistics provided additional confirmation by revealing how the distribution of energy levels changes as the disorder increases. This method is sensitive to the subtle effects of bond-breaking disorder, offering deeper insights into the role of local perturbations in driving localization.<\/span><\/p>

Our findings contribute to a more nuanced understanding of Anderson localization in disordered systems, particularly in the context of bond-breaking disorder. This work not only advances theoretical models of electronic transport in disordered systems but also has significant implications for the design of materials in nanoelectronics, quantum computing, and material science, where control over disorder plays a critical role in determining device properties.\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
