Densities probabilities of a Bose-Fermi Mixture in 1D Double well potential
J. Nisperuza, JP Rubio, R. Avella
We use the two mode approximation for a interacting one-dimensional spinless soft core bosons and one half spin fermions in a double-well potential with a large central barrier. We…
Bose-Fermi transmutation for one-dimensional harmonic trap
J. Nisperuza, J. P. Rubio, R. Avella
Using Density Matrix renormalization group (DMRG), we study the ground state properties of spin one-half fermions and scalar bosons in the soft-core limit, with weak s-wave inter a…
Mixture of scalar bosons and two-color fermions in one dimension: Superfluid-insulator transitions
R. Avella, J. J. Mendoza-Arenas, R. Franco +1
Superfluid-insulator transitions in a one-dimensional mixture of two-color fermions and scalar bosons are studied within the framework of the Bose-Fermi-Hubbard model. Zero-tempera…
Insulator phases of a mixture of spinor fermions and hard-core bosons
R. Avella, J. J. Mendoza-Arenas, R. Franco +1
We study numerically a one-dimensional mixture of spin- fermions and scalar bosons in the hard-core limit. Considering repulsive fermion-fermion and boson-fermion int…
