Abstract
Vacancies in materials structure, lowering its atomic density, take the system closer to the atomic limit, to which all systems are topologically trivial. Here we show a mechanism of mediated interaction between vacancies inducing a topologically nontrivial phase. We explore topological transition dependence with the vacancy density in transition metal dichalcogenides. As a case of...
