Few-body bound states of two-dimensional bosons
Guijarro Gámez, Grecia; Astrakharchik, Grigori; Boronat Medico, Jordi; Bazak, Betzalel; Petrov, D. S. (American Physical Society (APS), 2020-04-07)
Article
Accés obertWe 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
Guijarro Gámez, Grecia; Pricoupenko, A.; Astrakharchik, Grigori; Boronat Medico, Jordi; Petrov, D. S. (American Physical Society (APS), 2018-06-14)
Article
Accés obertWe 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, ... -
Quantum halo states in two-dimensional dipolar clusters
Guijarro Gámez, Grecia; Astrakharchik, Grigori; Boronat Medico, Jordi (Nature, 2021-12-01)
Article
Accés obertA halo is an intrinsically quantum object defined as a bound state of a spatial size which extends deeply into the classically forbidden region. Previously, halos have been observed in bound states of two and less frequently ... -
Quantum Monte Carlo study of few-and many-body bose systems in one and two dimensions
Guijarro Gámez, Grecia (Universitat Politècnica de Catalunya, 2020-12-21)
Tesi
Accés obertIn this Thesis, we report a detailed study of the ground-state properties of a set of quantum few- and many-body systems by using Quantum Monte Carlo methods. First, we introduced the Variational Monte Carlo and Diffusion ... -
Ultradilute quantum liquid of dipolar atoms in a bilayer
Guijarro Gámez, Grecia; Astrakharchik, Grigori; Boronat Medico, Jordi (American Institute of Physics (AIP), 2022-02-11)
Article
Accés obertWe show that ultradilute quantum liquids can be formed with ultracold bosonic dipolar atoms in a bilayer geometry. Contrary to previous realizations of ultradilute liquids, there is no need for stabilizing the system with ...
