Solitonic characteristics are revealed in the diffusion process of a hump or a notch wave packet in a one-dimensional Bose-Einstein condensate.By numerically so
Considering the non-locality of interactions in a Bose-Einstein condensate,the existence and stability of solitons subject to a PT-symmetric potential are discu
We develop a tightly focused pump-probe absorption technique to study diffusion dynamics of photoexcited carriers.It has many advantages including the simple se
