A Metal-Insulator transition induced by Random Dipoles
M. Larcher, C. Menotti, B. Tanatar +1
We study the localization properties of a test dipole feeling the disordered potential induced by dipolar impurities trapped at random positions in an optical lattice. This random…
Localization in momentum space of ultracold atoms in incommensurate lattices
Marco Larcher, Michele Modugno, Franco Dalfovo
We characterize the disorder induced localization in momentum space for ultracold atoms in one-dimensional incommensurate lattices, according to the dual Aubry-André model. For low…
Effects of interaction on the diffusion of atomic matter waves in one-dimensional quasi-periodic potentials
Marco Larcher, Franco Dalfovo, Michele Modugno
We study the behaviour of an ultracold atomic gas of bosons in a bichromatic lattice, where the weaker lattice is used as a source of disorder. We numerically solve a discretized m…
