• Elusive structure of helium trimers 

      Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (2016-08-23)
      Article
      Accés obert
      Over the years many He–He interaction potentials have been developed, some very sophisticated, including various corrections beyond the Born–Oppenheimer approximation. Most of them were used to predict properties of helium ...
    • Ground state of small mixed helium and spin-polarized tritium clusters: A quantum Monte Carlo study 

      Stipanovic, P.; Markic, L. Vranjes; Boronat Medico, Jordi; Kezic, B. (2011-02-07)
      Article
      Accés restringit per política de l'editorial
      We report results for the ground-state energy and structural properties of small 4He–T↓ clusters consisting of up to four T↓ and eight 4He atoms. These results have been obtained using very well-known 4He–4He and T↓– T↓ ...
    • Ground-state properties of weakly bound helium-alkali trimers 

      Stipanovic, P.; Vranješ Markic, Leandra; Zaric, D.; Boronat Medico, Jordi (2017-01-07)
      Article
      Accés obert
      Weakly bound triatomic molecules consisting of two helium atoms and one alkali metal atom are studied by means of the diffusion Monte Carlo method. We determined the stability of 4He2A, 4He3HeA, and 3He2A, where A is one ...
    • Quantum halo states in helium tetramers 

      Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (2017-01-12)
      Article
      Accés obert
      The universality of quantum halo states enables a comparison of systems from different fields of physics, as demonstrated in two- and three-body clusters. In the present work, we studied weakly bound helium tetramers in ...
    • Structure of halo and quasi-halo helium–helium–alkali trimers 

      Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (2017-05-01)
      Article
      Accés obert
      We report a diffusion Monte Carlo study of A4He2 and A4He3He trimers’ structural properties, were A is one of the alkali atoms 6,7Li, 23Na, 39K, 85Rb or 133Cs. Some of them are in a pure halo state, characterized by large ...
    • Ultradilute quantum liquid drops 

      Cikojevic, V.; Dželalija, K.; Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (American Physical Society, 2018-04-05)
      Article
      Accés obert
      Using quantum Monte Carlo methods we have studied dilute Bose-Bose mixtures with attractive interspecies interaction in the limit of zero temperature. The calculations are exact within some statistical noise and thus go ...
    • Universality in molecular halo clusters 

      Stipanovic, P.; Markic, L. Vranjes; Beslic, Ivana; Boronat Medico, Jordi (2014-12-16)
      Article
      Accés obert
      The ground state of weakly bound dimers and trimers with a radius extending well into the classically forbidden region is explored, with the goal to test the predicted universality of quantum halo states. The focus of the ...
    • Universality of size-energy ratio in four-body systems 

      Stipanovic, P.; Vranješ Markic, Leandra; Gudyma, Andrii; Boronat Medico, Jordi (Nature, 2019-04-18)
      Article
      Accés obert
      Universal relationship of scaled size and scaled energy, which was previously established for two- and three-body systems in their ground state, is examined for four-body systems, using Quantum Monte Carlo simulations. We ...
    • Van der Waals five-body size-energy universality 

      Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (Nature, 2022-12-01)
      Article
      Accés obert
      A universal relationship between scaled size and scaled energy is explored in five-body self-bound quantum systems. The ground-state binding energy and structure properties are obtained by means of the diffusion Monte Carlo ...
