Scattering bright solitons: quantum versus mean-field behavior
Bettina Gertjerenken, Thomas P. Billam, Lev Khaykovich +1
We investigate scattering bright solitons off a potential using both analytical and numerical methods. Our paper focuses on low kinetic energies for which differences between the m…
Inverse Energy Cascade in Forced 2D Quantum Turbulence
Matthew T. Reeves, Thomas P. Billam, Brian P. Anderson +1
We demonstrate an inverse energy cascade in a minimal model of forced 2D quantum vortex turbulence. We simulate the Gross-Pitaevskii equation for a moving superfluid subject to for…
Equilibrium solutions of immiscible two-species Bose-Einstein condensates in perturbed harmonic traps
R. W. Pattinson, T. P. Billam, S. A. Gardiner +5
We investigate the mean--field equilibrium solutions for a two--species immiscible Bose--Einstein condensate confined by a harmonic confinement with additional linear perturbations…
