    Antibonding ground state of adatom molecules in bulk Dirac semimetals 
    Marques, Y.; Obispo, A. E.; Ricco, L. S.; de Souza, M.; Shelykh, Ivan; Seridonio, A. C (American Physical Society (APS), 2017-07-11)
    The ground state of the diatomic molecules in nature is inevitably bonding, and its first excited state is antibonding. We demonstrate theoretically that, for a pair of distant adatoms placed buried in three-dimensional-Dirac semimetals, this natural ...

    Chiral magnetic chemical bonds in molecular states of impurities in Weyl semimetals 
    Marques, Y.; Mizobata, W. N.; Oliveira, R. S.; de Souza, M.; Figueira, M. S.; Shelykh, Ivan; Seridonio, A. C. (Springer Science and Business Media LLC, 2019-06-11)
    We demonstrate that chirality of the electron scattering in Weyl semimetals leads to the formation of magnetic chemical bonds for molecular states of a pair of impurities. The efect is associated with the presence of time-reversal symmetry breaking ...

    Resonant electron tunneling spectroscopy of antibonding states in a Dirac semimetal 
    Marques, Y.; Yudin, D.; Shelykh, Ivan; Seridonio, A. C. (American Physical Society (APS), 2018-06-12)
    Recently, it was shown both theoretically and experimentally that certain three-dimensional (3D) materials have Dirac points in the Brillouin zone, thus being 3D analogs of graphene. Moreover, it was suggested that under specific conditions a pair of ...
