    • Bauschinger effect in thin metal films: Discrete dislocation dynamics study 

      Davoudi, Kamyar M.; Nicola, Lucia; Vlassak, Joost J. (American Institute of Physics (AIP), 2014)
      The effects of dislocation climb on plastic deformation during loading and unloading are studied using a two-dimensional discrete dislocation dynamics model. Simulations are performed for polycrystalline thin films ...

    • Elastic scattering and rotational excitation of nitrogen molecules by sodium atoms 

      Loreau, Jérome; Zhang, Peng; Dalgarno, Alexander (AIP Publishing, 2011)
      A quantal study of the rotational excitation of nitrogen molecules by sodium atoms is carried out. We present the two-dimensional potential energy surface of the NaN2 complex, with the N2 molecule treated as a rigid rotor. ...

    • Foldable structures and the natural design of pollen grains 

      Katifori, Eleni; Alben, Silas; Cerda, Enrique; Nelson, David R.; Dumais, Jacques (Proceedings of the National Academy of Sciences, 2010)
      Upon release from the anther, pollen grains of angiosperm flowers are exposed to a dry environment and dehydrate. To survive this process, pollen grains possess a variety of physiological and structural adaptations. Perhaps ...

    • He–ThO(1Σ+) Interactions at Low Temperatures: Elastic and Inelastic Collisions, Transport Properties, and Complex Formation in Cold 4He Gas 

      Tscherbul, T. V.; Sayfutyarova, E. R.; Buchachenko, A. A.; Dalgarno, Alexander (AIP Publishing, 2011)
      We present an ab initio study of cold 4He + ThO(1Σ+) collisions based on an accurate potential energy surface (PES) evaluated by the coupled cluster method with single, double, and noniterative triple excitations using an ...

    • Scattering of nitrogen molecules by silver atoms 

      Loreau, Jérôme; Zhang, Peng; Dalgarno, Alexander (AIP Publishing, 2012)
      We present a quantal study of the rotationally elastic and inelastic scattering of Ag and N(2), with the nitrogen molecule treated as a rigid rotor. The two-dimensional potential energy surface of the AgN(2) complex is ...
