When sense bridges cognition, emotion and aims: developing a new framework to study sense in organization research.
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
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
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
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
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
