Event description:
Simulating ferromagnetic chains with condensates: Solitons that wouldn’t speed up
Solitons are wave packets that maintain their shape during free propagation due to a non-linearity that prevents the usual spreading. In a 1D Bose-Einstein condensate, this non-linear element is provided by interactions, resulting in the observation of bright and dark solitons for attractive and repulsive gases, respectively. After reviewing the basic physics of soliton formation, I will show that working with mixtures of condensates opens up a much richer physics, with the emergence of magnetic solitons that exhibit counter-intuitive and surprising behaviors.
