Modeling the transport of interacting matter-waves in disorder by a non-linear diffusion equation
Eleonora Lucioni, Luca Tanzi, Chiara D'Errico +3
We model the expansion of an interacting atomic Bose-Einstein condensate in a disordered lattice with a nonlinear diffusion equation normally used for a variety of classical system…
Quantum diffusion with disorder, noise and interaction
C. D'Errico, M. Moratti, E. Lucioni +6
Disorder, noise and interaction play a crucial role in the transport properties of real systems, but they are typically hard to control and study both theoretically and experimenta…
Localization from quantum interference in one-dimensional disordered potentials
Marco Moratti, Michele Modugno
We show that the tails of the asymptotic density distribution of a quantum wave packet that localizes in the the presence of random or quasiperiodic disorder can be described by th…
Nonlinear quantum model for atomic Josephson junctions with one and two bosonic species
Giovanni Mazzarella, Marco Moratti, Luca Salasnich +1
We study atomic Josephson junctions (AJJs) with one and two bosonic species confined by a double-well potential. Proceeding from the second quantized Hamiltonian, we show that it i…
Atomic Josephson junction with two bosonic species
Giovanni Mazzarella, Marco Moratti, Luca Salasnich +2
We study an atomic Josephson junction (AJJ) in presence of two interacting Bose-Einstein condensates (BECs) confined in a double well trap. We assume that bosons of different speci…
