    • Exact ground-state behavior of a four-atom generalized Hubbard model 
      Rössler, J.; Fernndez, B.; Kiwi, M. (1981)
      The exact ground state of a four-atom system described by the generalized form of the Hubbard Hamiltonian is obtained. Next, the solution is used to extract relevant physical information on the dynamics of the cluster ...
    • Polycrystalline Ni nanotubes under compression: a molecular dynamics study 
      Rojas Núñez, J.; Baltazar, S. E.; González, R. I.; Bringa, E. M.; Allende, S.; Kiwi, M.; Valencia, F. J. (Nature, 2020)
      Mechanical properties of nanomaterials, such as nanowires and nanotubes, are an important feature for the design of novel electromechanical nano-architectures. Since grain boundary structures and surface modifications can ...
