Using a standing light wave potential, a stable quasi-one-dimensional attractive dilute-gas Bose-Einstein condensate can be realized in a mean-field approximation by the cubic nonlinear Schrödinger equation with attractive nonlinearity and an elliptic function potential.
Dynamics of vortex dipoles in confined BoseEinstein condensates
Characteristics of two-dimensional quantum turbulence in a compressible superfluid.
This work finds conditions for which small-scale stirring of the condensate generates disordered 2D vortex distributions that dissipatively evolve toward persistent currents, indicating energy transport from small to large length scales.
Simulation of the effect of wind speedup in the formation of transverse dune fields
A computer simulation model for transverse-dune-field dynamics, corresponding to a uni-directional wind regime, is developed. In a previous formulation, two distinct problems were found regarding the…
Multistable Solitons in Higher-Dimensional Cubic-Quintic Nonlinear Schrödinger Lattices
Modelling Desert Dune Fields Based on Discrete Dynamics
A mathematical formulation is developed to model the dynamics of sand dunes. The physical processes display strong non-linearity that has been taken into account in the model. When assessing the…
