Dynamics of equilibration and collisions in ultradilute quantum droplets

Employing time-dependent density-functional theory, we have studied dynamical equilibration and binary head-on collisions of quantum droplets taking as a case of study droplets made of a 39 K - 39 K Bose mixture. The phase space of collision outcomes is extensively explored by performing fully three...
