This week’s Image of the Week comes from a recent JPhysA paper, Dynamics of trapped interacting vortices in Bose–Einstein condensates: a role of breathing degree of freedom.  Researchers from National University of Uzbekistan, Osaka City University, Turin Polytechnic University in Tashkent, Kyoto University and Bharathidasan University investigate the “role of breathing width degree of freedom in the effective theory of interacting vortices in a trapped single-component Bose–Einstein condensates in two dimensions, under strong repulsive cubic nonlinearity”.
