Probing non-locality of interactions in a Bose–Einstein condensate using solitons
Probing non-locality of interactions in a Bose–Einstein condensate using solitons
We consider a Bose–Einstein condensate (BEC) with non-local inter-particle interactions. The local Gross–Pitaevskii (GP) equation is valid for the gas parameter , but for , the BEC is described by a modified GP equation (MGPE). We study the exact solutions of the MGPE describing bright and dark solitons. It turns …
