High-Temperature Atomic Superfluidity in Lattice Boson-Fermion Mixtures
F. Illuminati, A. Albus
We consider atomic Bose-Fermi mixtures in optical lattices and study the superfluidity of fermionic atoms due to s-wave pairing induced by boson-fermion interactions. We prove that…
Mixtures of Bosonic and Fermionic Atoms in Optical Lattices
Alexander Albus, Fabrizio Illuminati, Jens Eisert
We discuss the theory of mixtures of Bosonic and Fermionic atoms in periodic potentials at zero temperature. We derive a general Bose--Fermi Hubbard Hamiltonian in a one--dimension…
Ground-state properties of trapped Bose-Fermi mixtures: role of exchange-correlation
Alexander P. Albus, Fabrizio Illuminati, Martin Wilkens
We introduce Density Functional Theory for inhomogeneous Bose-Fermi mixtures, derive the associated Kohn-Sham equations, and determine the exchange-correlation energy in local dens…
Critical temperature of Bose-Einstein condensation in trapped atomic Bose-Fermi mixtures
Alexander P. Albus, Stefano Giorgini, Fabrizio Illuminati +1
We calculate the shift in the critical temperature of Bose-Einstein condensation for a dilute Bose-Fermi mixture confined by a harmonic potential to lowest order in both the Bose-B…
