Implementation of the Linear Method for the optimization of Jastrow-Feenberg and Backflow Correlations
M. Motta, G. Bertaina, D. E. Galli +1
We present a fully detailed and highly performing implementation of the Linear Method [J. Toulouse and C. J. Umrigar (2007)] to optimize Jastrow-Feenberg and Backflow Correlations…
Energy of strongly attractive Bose-Fermi mixtures
Andrea Guidini, Elisa Fratini, Gianluca Bertaina +1
We discuss how approximate theories for Bose-Fermi mixtures recover in the molecular limit the expected expression for Fermi-Fermi mixtures of molecules and unpaired fermions. In p…
One-dimensional liquid He: dynamical properties beyond Luttinger liquid theory
G. Bertaina, M. Motta, M. Rossi +2
We compute the zero-temperature dynamical structure factor of one-dimensional liquid He by means of state-of-the-art Quantum Monte Carlo and analytic continuation techniques. B…
Condensed phase of Bose-Fermi mixtures with a pairing interaction
Andrea Guidini, Gianluca Bertaina, Davide Emilio Galli +1
We study the condensed phase of a Bose-Fermi mixture with a tunable pairing interaction between bosons and fermions with many-body diagrammatic methods and fixed-node diffusion Qua…
Quantum Monte Carlo study of the indirect Pauli exclusion effect in Bose-Fermi mixtures
G. Bertaina, A. Guidini, P. Pieri
We study the momentum distributions of a three-dimensional resonant Bose-Fermi mixture in the molecular limit at zero temperature. For concentration of the bosons with respect to t…
Bose-Fermi mixtures in the molecular limit
A. Guidini, G. Bertaina, E. Fratini +1
We consider a Bose-Fermi mixture in the molecular limit of the attractive interaction between fermions and bosons. For a boson density smaller or equal to the fermion density, we s…
