• Contact and static structure factor for bosonic and fermionic mixtures 

      Barfknecht, Rafael Emilio; Brouzos, Ioannis; Foerster, Angela (2015) [Artigo de periódico]
      We study measurable quantities of bosonic and fermionic mixtures on a one-dimensional ring. These few-body ensembles consist of majority atoms obeying certain statistics (Fermi or Bose) and an impurity atom in a different ...
    • Trace of broken integrability in stationary correlation properties 

      Brouzos, Ioannis; Foerster, Angela (2014) [Artigo de periódico]
      We show that the breaking of integrability in the fundamental one-dimensional model of bosons with contact interactions has consequences on the stationary correlation properties of the system. We calculate the energies and ...
