Quantum Monte Carlo simulation of three-dimensional Bose-Fermi mixtures

Understand

Exploratory simulations of Bose-Fermi mixtures on the three-dimensional optical lattice at finite temperature are performed by adopting the lattice quantum chromodynamics technique.

• We analyze the bosonic superfluid transition and its dependence on the strength of the boson-fermion coupling.
• The particle densities and the pair occupancies are also studied to understand the effect of the boson-fermion coupling to the microscopic properties of the system.
• Effect of the induced fermion-fermion interaction by the boson density fluctuation is clearly seen.
