• Abstract: We study the two-dimensional Bose-Fermi mixture on square lattice at finite temperature by using the determinant quantum Monte Carlo method within the weakly interacting regime. Here we consider the attractive Bose-Hubbard model and free spinless fermions. In the absence of bosonfermion interactions, we obtain the boundary of the collapsed state of the attractive bosons. In the presence of boson-fermion interactions, an effective p-wave interaction between fermions will be induced as far as the bosons are in a superfluid state. Moreover, we find the emergence of the composite fermion pairs at low temperatures.

  We demonstrate atom-resolved detection of itinerant bosonic $23$Na and fermionic $6$Li quantum gases. In contrast to prior work on lattice-trapped gases, here we realize microscopy of quantum gases in the continuum. Our technique opens the door to the atom-resolved study of strongly correlated quantum gases of bosons, fermions, and their mixtures.

• Probing pair correlations in Fermi gases with Ramsey-Bragg interferometry [41.94295877935867]
  We propose an interferometric method to probe pair correlations in a gas of spin-1/2 fermions. The method consists of a Ramsey sequence where both spin states of the Fermi gas are set in a superposition of a state at rest and a state with a large recoil velocity. The off-diagonal long-range order is directly reflected in the behavior of the interferometric signal for long interrogation times.

  We report the observation of the long-sought pair-fluctuation-driven pseudogap in homogeneous unitary Fermi gases of lithium-6 atoms. The inverse pair lifetime exhibits a thermally-activated exponential behavior, uncovering the microscopic virtual pair breaking and recombination mechanism. Our findings quantitatively characterize the pseudogap in strongly-interacting Fermi gases, highlighting the role of preformed pairing as a precursor to superfluidity.

  We study the collective oscillations of spin-polarized fermionic impurities immersed in a Bose-Einstein condensate. For strong interactions, the Fermi gas perfectly mimics the superfluid hydrodynamic modes of the condensate. With an increasing number of bosonic thermal excitations, the dynamics of the impurities cross over from the collisionless to the hydrodynamic regime.

• Exploring phonon-like interactions in one-dimensional Bose-Fermi mixtures [0.0]
  We investigate a cold atomic Bose-Fermi mixture confined in an optical lattice potential solely affecting the bosons. Under attractive Bose-Fermi interaction, the insulating phase may adopt a fermionic wedding-cake-like configuration. For repulsive interaction, the trap destabilizes the Peierls phase, causing the two species to separate.

Our discussion includes: modifications to the ground state and excitation spectrum, critical behaviour near the Bose--Einstein condensation temperature, the unitary regime where the interactions are as strong as allowed by quantum mechanics.
