For mixtures of Bose and Fermi alkali-metal atoms, the fermion degrees of freedom can be integrated out in their finite temperature partition function. The final result can be expanded as a power series in the boson density. Under appropriate conditions, the pairwise interaction between the bosons can be changed from positive to negative by the fermion-mediated term at a low enough temperature. The boson cloud may then collapse. For attractive fermion-boson interactions, there is also a… Expand
Vortex state in a Bose-Fermi mixture with attraction between bosons and fermions
An effective Hamiltonian for the Bose subsystem for the mixture of ultracold atomic clouds of bosons and fermions is obtained by integrating out the fermion degrees of freedom. Using the effectiveExpand
Mixtures of correlated bosons and fermions: Dynamical mean-field theory for normal and condensed phases
We derive a dynamical mean-field theory for mixtures of interacting bosons and fermions on a lattice (BF-DMFT). The BF-DMFT is a comprehensive, thermodynamically consistent framework for theExpand
Stable and unstable regimes in Bose-Fermi mixtures with attraction between components
The collapse of a trapped boson-fermion mixture with attraction between bosons and fermions is investigated in the framework of the effective Hamiltonian for the Bose system. The properties of anExpand
On the critical temperature in a Boson-Fermion mixture with attraction between the components
The dependence of the critical temperature shift in the Bose component of a degenerate Bose-Fermi gas mixture in a harmonic trap on the number of bosons and fermions has been obtained on the basis ofExpand
Effective Hamiltonian study of excitations in a boson?fermion mixture with attraction between components
An effective Hamiltonian for the Bose subsystem in the mixture of ultracold atomic clouds of bosons and fermions with mutual attractive interaction is used for investigating the collective excitationExpand
Observation of fermion-mediated interactions between bosonic atoms
TLDR
It is shown that, when a Bose–Einstein condensate of caesium atoms is embedded in a degenerate Fermi gas of lithium atoms, interspecies interactions can give rise to an effective trapping potential, damping, and attractive boson–boson interactions mediated by fermions. Expand
Structure and stability of quasi-two-dimensional boson–fermion mixtures with vortex–antivortex superposed states
We investigate the equilibrium properties of a quasi-two-dimensional degenerate boson-fermion mixture (DBFM) with a bosonic vortex-antivortex superposed state (VAVSS) using a quantum-hydrodynamicExpand
Collapse mechanism of the condensate wavefunction in the Bose-Fermi mixture with attraction between the components
The ground state of the mixture of degenerate Bose and Fermi atoms in a trap has been analyzed on the basis of the effective Hamiltonian. The two types of the solutions of the modifiedExpand
Stability of the Bose system in Bose-Fermi mixture with attraction between bosons and fermions
An effective Hamiltonian for the Bose system in the mixture of ultracold atomic clouds of bosons and fermions is obtained by integrating out the Fermi degrees of freedom. An instability of the BoseExpand
Density and stability in ultracold dilute boson-fermion mixtures
Abstract. We analyze in detail recent experiments on ultracold dilute 87Rb–40K mixtures in Hamburg and in Florence within a mean-field theory. To this end we determine how the stationary bosonic andExpand
