    This papers looks at the concept of sense to tackle management and organization science questions. It discusses the theoretical and methodological basis of the concept of sense to provide a new framework to study sense in organizational research. The interested of the new framework is tested in practice through a case study that aims at understanding the suffering of project managers.bridges cognition; organization research;

    Decoherence effects in the dynamics of interacting ultracold bosons in disordered lattices

    Full text link
    We study the interplay between disorder, interactions and decoherence induced by spontaneous emission process. Interactions are included in the Anderson model via a mean-field approximation, and a simple model for spontaneous emission is introduced. Numerical simulations allow us to study the effects of decoherence on different dynamical regimes. Physical pictures for the mechanisms at play are discussed and provide simple interpretations. Finally, we discuss the validity of scaling laws on the initial state width

    Emergence of nonlinear behavior in the dynamics of ultracold bosons

    Full text link
    We study the evolution of a system of interacting ultracold bosons, which presents nonlinear, chaotic, behaviors in the limit of very large number of particles. Using the spectral entropy as an indicator of chaos and three different numerical approaches : Exact diagonalization, truncated Husimi method and mean-field (Gross-Pitaevskii) approximation, we put into evidence the destructive impact of quantum noise on the emergence of the nonlinear dynamics

    Kicked-rotor quantum resonances in position space: Application to situations of experimental interest

    Full text link
    In this work we apply the formalism developed in [M. Lepers \emph{et al}., Phys. Rev. A \textbf{77}, 043628 (2008)] to different initial conditions corresponding to systems usually met in real-life experiments, and calculate the observable quantities that can be used to characterize the dynamics of the system. The position space point of view allows highly intuitive pictures of the physics at play.Comment: accepted in Eur. Phys. J.

    A quantum motor: directed wavepacket motion in an optical lattice

    Full text link
    We propose a method for arbitrary manipulations of a quantum wavepacket in an optical lattice by a suitable modulation of the lattice amplitude. A theoretical model allows to determine the modulation corresponding to a given wavepacket motion, so that arbitrary atomic trajectories can be generated. The method is immediately usable in state of the art experiments
