Elusive structure of helium trimers
Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (20160823)
Article
Open AccessOver 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 ... 
Finiterange effects in ultradilute quantum drops
Cikojevic, Viktor; Vranješ Markic, Leandra; Boronat Medico, Jordi (20200527)
Article
Open AccessIn the first experimental realization of dilute Bose–Bose liquid drops using two hyperfine states of 39K some discrepancies between theory and experiment were observed. The standard analysis of the data using the Lee–Huang–Yang ... 
Groundstate properties of weakly bound heliumalkali trimers
Stipanovic, P.; Vranješ Markic, Leandra; Zaric, D.; Boronat Medico, Jordi (20170107)
Article
Open AccessWeakly 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 ... 
One dimensional H1, H2 and H3
Vidal, A.J.; Astrakharchik, Grigori; Vranješ Markic, Leandra; Boronat, J. (20160526)
Article
Open AccessThe groundstate properties of onedimensional electronspinpolarized hydrogen H1, deuterium H2, and tritium 3 Hare obtained by means of quantum Monte Carlo methods. The equations of state of the three isotopes are ... 
Quantum halo states in helium tetramers
Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (20170112)
Article
Open AccessThe universality of quantum halo states enables a comparison of systems from different fields of physics, as demonstrated in two and threebody clusters. In the present work, we studied weakly bound helium tetramers in ... 
Spinpolarized hydrogen adsorbed on the surface of superfluid He4
Marín, J. M.; Vranješ Markic, Leandra; Boronat Medico, Jordi (20131214)
Article
Open AccessThe experimental realization of a thin layer of spinpolarized hydrogen H double down arrow adsorbed on top of the surface of superfluid He4 provides one of the best examples of a stable, nearly twodimensional(2D) quantum ... 
Structure of halo and quasihalo helium–helium–alkali trimers
Stipanovic, P.; Vranješ Markic, Leandra; Boronat Medico, Jordi (20170501)
Article
Open AccessWe 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 ... 
Towards a quantum Monte Carlobased density functional including finiterange effects: excitation modes of a K 39 quantum droplet
Cikojevic, Viktor; Vranješ Markic, Leandra; Pi Pericay, Martí; Barranco Gómez, Manuel; Boronat Medico, Jordi (American Physical Society, 20200925)
Article
Open AccessSome discrepancies between experimental results on quantum droplets made of a mixture of 39K atoms in different hyperfine states and their analysis within extended GrossPitaevskii theory (which incorporates beyond meanfield ... 
Trapped BoseBose mixtures at finite temperature: a quantum Monte Carlo approach
Dželalija, K.; Cikojevic, V.; Boronat Medico, Jordi; Vranješ Markic, Leandra (American Physical Society, 20201204)
Article
Open AccessWe study thermal properties of a trapped BoseBose mixture in a dilute regime using quantum Monte Carlo methods. Our main aim is to investigate the dependence of the superfluid density and the condensate fraction on ... 
Twodimensional Spinpolarized hydrogen at zero temperature
Vranješ Markic, Leandra; Boronat Medico, Jordi (201306)
Article
Open AccessThe groundstate properties of spin polarized hydrogen H↓ in two dimensions (2D) are obtained by means of diffusion Monte Carlo calculations. Using the most accurate to date ab initio H↓–H↓ interatomic potential we have ... 
Ultradilute quantum liquid drops
