Emergence and Stability of Vortex Clusters in Bose-Einstein Condensates: a Bifurcation Approach near the Linear Limit
Bose-Einstein condensates Vortices Dark solitons Bifurcations

We study the existence and stability properties of clusters of alternating charge vortices in Bose-Einstein condensates. It is illustrated that such states emerge from cascades of symmetry-breaking bi...
Impact of anisotropy on vortex clusters and their dynamics
Impact of anisotropy vortex clusters their dynamics

We investigate the e ects of anisotropy on the stability and dynamics of vortex cluster states
which arise in Bose-Einstein condensates. Suciently strong anisotropies are shown to stabilize states w...
This paper applies the Hamiltonian Approach (HA) to two-dimensional motions of incompressible fluid in curvi-linear coordinates, in particular on a sphere. The HA has been used to formulate governing ...
