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 ...
Towards a quantum Monte Carlo-based density functional including finite-range 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, 2020-09-25)
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 Gross-Pitaevskii theory (which incorporates beyond mean-field ...
