We demonstrate theoretically that, for a pair of distant adatoms placed buried in three-dimensional-Dirac semimetals, this natural order of the states can be reversed and an antibonding ground state occurs at the lowest energy of the so-called bound states in the continuum. We propose an experimental protocol with the use of a scanning tunneling microscope tip to visualize the topographic map of the local density of states on the surface of the system to reveal the emerging physics.041112eninfo:eu-repo/semantics/openAccessSemimetalsDirac semimetalAnderson impurity modelGreen's function methodsCondensed Matter & Materials PhysicsMálmungarÞéttefnisfræðiAntibonding ground state of adatom molecules in bulk Dirac semimetalsinfo:eu-repo/semantics/articlePhysical Review B10.1103/PhysRevB.96.041112
