Parallel finite-element codes for the Bogoliubov-de Gennes stability analysis of Bose-Einstein condensates
Georges Sadaka, Pierre Jolivet, Efstathios G. Charalampidis +1
We present and distribute a parallel finite-element toolbox written in the free software FreeFem for computing the Bogoliubov-de Gennes (BdG) spectrum of stationary solutions to on…
A finite element toolbox for the Bogoliubov-de Gennes stability analysis of Bose-Einstein condensates
Georges Sadaka, Victor Kalt, Ionut Danaila +1
We present a finite element toolbox for the computation of Bogoliubov-de Gennes modes used to assess the linear stability of stationary solutions of the Gross-Pitaevskii (GP) equat…
Coupling Navier-Stokes and Gross-Pitaevskii equations for the numerical simulation of two-fluid quantum flows
Marc Brachet, Georges Sadaka, Zhentong Zhang +2
Numerical methods for solving the Navier-Stokes equations for classical (or normal) viscous fluids are well established. This is also the case for the Gross-Pitaevskii equation, go…
Identification of vortices in quantum fluids: finite element algorithms and programs
Victor Kalt, Georges Sadaka, Ionut Danaila +1
We present finite-element numerical algorithms for the identification of vortices in quantum fluids described by a macroscopic complex wave function. Their implementation using the…
Nonlinear dynamics of coupled superfluids
S Laurent, P. Parnaudeau, F. Chevy +1
Following recent experiments on ultracold dual superflows, we model in this work the dynamics of two harmonically trapped counterflowing superfluids. Using complementary analytical…
Vector Dark-Antidark Solitary Waves in Multi-Component Bose-Einstein condensates
I. Danaila, M. A. Khamehchi, V. Gokhroo +2
Multi-component Bose-Einstein condensates exhibit an intriguing variety of nonlinear structures. In recent theoretical work, the notion of magnetic solitons has been introduced. He…
