Quantum Monte Carlo and perturbative study of two-dimensional Bose-Fermi mixtures

Year: 2024

Type: article

Abstract: The authors investigate the thermodynamic properties of a two-dimensional dilute Bose-Fermi mixture of ultracold atoms at zero temperature through two complementary methods: perturbation theory to the second order in the interactions and quantum Monte Carlo. They find good agreement between analytic expressions and numerical results for weak interactions, while significant discrepancies appear in the regime close to mechanical instability, indicating phase separation of the bosonic component.
