Dynamical instability of a boson-fermion mixture at low dimensions
(Elsevier Science Bv, 2009)We examine theoretically the dynamical response of a homogeneous mixture of condensed bosons and spin-polarized fermions confined inside a quasi-two-dimensional or a quasi-one-dimensional geometry, considering quasi-thre ... -
Localization-delocalization transition in the random dimer model
(Amer Physical Soc, 2010)The random-dimer model is probably the most popular model for a one-dimensional disordered system where correlations are responsible for delocalization of the wave functions. This is the primary model used to justify the ... -
Condensation of two-dimensional harmonically confined bosons with Bessel-type interactions
(Amer Physical Soc, 2011)We study the ground-state configurations of few interacting bosons confined in two dimensions by anisotropic harmonic potentials. By means of variational calculations, including correlation effects, we show that the ... -
Anderson localization in optical lattices with speckle disorder
(Amer Physical Soc, 2011)We study the localization properties of noninteracting waves propagating in a speckle-like potential superposed on a one-dimensional lattice. Using a combined decimation-renormalization procedure, we estimate the localization ... -
