  • Elastic constants of incommensurate solid 4He from diffusion Monte Carlo simulations 

    Cazorla Silva, Claudio; Lutsyshyn, Yaroslav; Boronat Medico, Jordi (2013-06-28)
    Open Access
    We study the elastic properties of incommensurate solid 4He in the limit of zero temperature. Specifically, we calculate the pressure dependence of the five elastic constants (C11, C12, C13, C33, and C44), longitudinal and ...
  • On the stability of small vacancy clusters in solid 4He 

    Lutsyshyn, Yaroslav; Rota, Riccardo; Boronat Medico, Jordi (2011-03)
    Restricted access - publisher's policy
    We study numerically properties of multiple vacancies in solid 4He at zero temperature. Up to four vacancies were introduced into the solid through incommensuration between the number of available lattice sites and the ...
