• #### Collective excitations of a one-dimensional quantum droplet ﻿

(2020-05-21)
Article
Open Access
We calculate the excitation spectrum of a one-dimensional self-bound quantum droplet in a two-component bosonic mixture described by the Gross-Pitaevskii equation (GPE) with cubic and quadratic nonlinearities. The cubic ...
• #### Few-body bound states of two-dimensional bosons ﻿

(American Physical Society (APS), 2020-04-07)
Article
Open Access
We study clusters of the type $A_NB_M$ with N=M=3 in a two-dimensional mixture of A and B bosons, with attractive AB and equally repulsive AA and BB interactions. In order to check universal aspects of the problem, we ...
• #### One-dimensional three-boson problem with two- and three-body interactions ﻿

(American Physical Society (APS), 2018-06-14)
Article
Open Access
We solve the three-boson problem with contact two- and three-body interactions in one dimension and analytically calculate the ground and excited trimer-state energies. Then, by using the diffusion Monte Carlo technique, ...
• #### Ultradilute low-dimensional liquids ﻿

(2016-09-01)
Article
Open Access
We calculate the energy of one- and two-dimensional weakly interacting Bose-Bose mixtures analytically in the Bogoliubov approximation and by using the diffusion Monte Carlo technique. We show that in the case of attractive ...
